In selected pigment-printing formulas, a small proportion of Carboxymethyl Cellulose (CMC) or Carboxymethyl Starch (CMS) can be evaluated as a supporting rheology component while acrylic thickener remains the main low-solids synthetic route. The purpose is not to replace acrylic thickener by weight or to blend polymers because one raw material is cheaper. A successful compound system gives each polymer a defined function, controls total polymer solids, remains compatible with pigment and binder, and is validated through complete-paste rheology, holding stability, screen printing, rubbing fastness and finished fabric hand.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-3c1592f8\">When Should Acrylic Thickener Be Blended with CMC or CMS?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ca7f19c6\">A compound system is worth testing when the acrylic-only reference paste is commercially acceptable but still has one clearly defined weakness.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7267c787\">Typical reasons to investigate a blend include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Insufficient low-shear body at the desired acrylic dosage<\/li>\n\n\n\n<li>A need to modify penetration or water retention<\/li>\n\n\n\n<li>A need to change high-shear \/ low-shear balance<\/li>\n\n\n\n<li>A cost target that cannot be reached by acrylic dosage adjustment alone<\/li>\n\n\n\n<li>A desire to reduce stringing or alter recovery in a specific formula<\/li>\n\n\n\n<li>A need for a different paste-body profile on a particular fabric or screen<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e8ea1992\">The decision logic should be:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ec51bc4a\"><strong>Define the Acrylic-Only Weakness \u2192 Select CMC or CMS for a Specific Function \u2192 Build a Controlled Blend Ladder \u2192 Test the Complete Pigment Paste \u2192 Print \u2192 Evaluate Fastness and Hand \u2192 Compare Total Cost in Use<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0435d72b\">Do not begin with:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2a64323e\"><strong>\u201cReplace 30% of the acrylic with the cheaper polymer.\u201d<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2f935780\">A compound thickener should be designed around performance first and cost second.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-64b4cd39\">What Is a Compound Synthetic Thickener System?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2ad75494\">A compound thickener combines two or more rheology-control polymers in one printing formulation.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ffe6b740\">In the context of this article, the system contains:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-22b89b84\"><strong>Acrylic Synthetic Thickener<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-518c1f02\">plus selected:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CMC<\/li>\n\n\n\n<li>CMS<\/li>\n\n\n\n<li>or, in some development programs, both CMC and CMS<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-98dbf30a\">The components are not expected to perform identical jobs.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2829c208\">A well-designed blend uses:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c565ef1c\"><strong>Different Polymer Functions \u2192 One Application-Specific Rheology Profile<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-69ecb657\">FSX Chemical\u2019s current textile-thickener guidance also positions CMC and CMS as possible components in selected compound systems rather than universal direct replacements.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-3286fc08\">Why Blend Instead of Using One Thickener?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-cd201464\">No polymer automatically gives the ideal combination of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Low dosage<\/li>\n\n\n\n<li>Low-shear body<\/li>\n\n\n\n<li>High-shear flow<\/li>\n\n\n\n<li>Recovery<\/li>\n\n\n\n<li>Water retention<\/li>\n\n\n\n<li>Tolerancia a los electrolitos<\/li>\n\n\n\n<li>Compatibilidad con aglutinantes<\/li>\n\n\n\n<li>Soft hand<\/li>\n\n\n\n<li>Low cost<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1d216623\">Mixed-thickener studies in textile printing show that changing the thickener combination can change paste add-on, penetration and rheology.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c1843901\">Those published results are often from dye-printing systems rather than pigment printing, so they should not be copied directly into a pigment formula.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c802e77d\">They support a more general principle:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9e261600\"><strong>Changing Polymer Ratio Changes the Flow System.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fdf5debb\">For pigment printing, the blend must therefore earn its place through the actual pigment \/ binder trial.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-62fda3ef\">When Should You Not Use a Compound System?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-adacc6d9\">Do not add CMC or CMS simply because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The powder price is lower.<\/li>\n\n\n\n<li>The acrylic thickener looks expensive per kilogram.<\/li>\n\n\n\n<li>The acrylic-only paste already performs well.<\/li>\n\n\n\n<li>A competitor uses a mixed thickener.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3ddb0967\">A blend can add:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>More preparation steps<\/li>\n\n\n\n<li>Powder hydration risk<\/li>\n\n\n\n<li>More polymer solids<\/li>\n\n\n\n<li>More filtration risk<\/li>\n\n\n\n<li>More batch-to-batch variables<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7f3a168b\">If the acrylic-only system already gives:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Stable rheology<\/li>\n\n\n\n<li>Clean screen running<\/li>\n\n\n\n<li>Low working dosage<\/li>\n\n\n\n<li>Soft hand<\/li>\n\n\n\n<li>Required fastness<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6c981282\">then a compound route should only be adopted if it proves a measurable commercial advantage.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-741bc2c0\">What Role Should Acrylic Thickener Play?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ec9e8459\">Acrylic thickener is usually the main low-solids rheology-control component in conventional pigment printing.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-dee4b01c\">Depending on grade, it can provide:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Efficient viscosity development<\/li>\n\n\n\n<li>Strong shear thinning<\/li>\n\n\n\n<li>Controlled structural recovery<\/li>\n\n\n\n<li>Low working dosage<\/li>\n\n\n\n<li>Good pigment \/ binder compatibility in matched systems<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7933eb7f\">In a compound system, acrylic thickener often remains responsible for the core:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9b4c7008\"><strong>Screen-Printing Rheology<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e9cdadee\">while CMC or CMS is added to shift one or more secondary properties.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e4dab28f\">This is generally a safer development logic than asking CMC or CMS to replace the acrylic route completely without reformulation.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-7a097340\">What Role Can CMC Play?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f17ca5a9\">CMC is a water-soluble cellulose derivative available in a wide range of viscosity, degree-of-substitution and purity grades.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-acf7dcbc\">In selected pigment-printing compound systems, CMC may be evaluated for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Paste-body adjustment<\/li>\n\n\n\n<li>Water retention<\/li>\n\n\n\n<li>Low-shear viscosity support<\/li>\n\n\n\n<li>Penetration control<\/li>\n\n\n\n<li>Cost-performance adjustment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-47653ea9\">But CMC is an anionic polymer and its behavior can change with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Electrolytes<\/li>\n\n\n\n<li>Calcium \/ magnesium<\/li>\n\n\n\n<li>Binder ionicity<\/li>\n\n\n\n<li>Cationic fixers<\/li>\n\n\n\n<li>pH<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3f5ed4ba\">FSX Chemical\u2019s current CMC pigment-printing guidance therefore recommends complete-paste testing rather than selection from pure-water viscosity alone.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-37c542d0\">CMC should be treated as a supporting rheology polymer\u2014not as the pigment binder.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-1048134b\">What Role Can CMS Play?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d1d01e84\">CMS is a modified starch derivative and is itself a product family rather than one universal material.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1a47eddb\">Selected CMS grades may be evaluated in compound pigment-printing systems for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Viscosity support<\/li>\n\n\n\n<li>Paste-body modification<\/li>\n\n\n\n<li>Water retention<\/li>\n\n\n\n<li>Suspension support<\/li>\n\n\n\n<li>Cost-performance adjustment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4eb3ad3c\">FSX Chemical\u2019s current CMS guidance also identifies blended-thickener systems as a relevant development route.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-aadbffe2\">However, CMS behavior depends on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Starch source<\/li>\n\n\n\n<li>Grado de sustituci\u00f3n<\/li>\n\n\n\n<li>Molecular structure<\/li>\n\n\n\n<li>Viscosity grade<\/li>\n\n\n\n<li>Hidrataci\u00f3n<\/li>\n\n\n\n<li>Filtraci\u00f3n<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9aa522ac\">Therefore:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-bc980277\"><strong>CMS Grade A \u2260 CMS Grade B.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7b3e062c\">Use an application-specific grade and verify it with the actual pigment \/ binder formula.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-ee874731\">CMC vs. CMS as a Secondary Blend Component<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table

not a ranking.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ebfdcae4\">The better secondary polymer depends on the specific weakness of the acrylic-only reference paste.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-8a784207\">Why Polymer Blends Do Not Guarantee Synergy<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a9de33e6\">Blending two thickeners does not guarantee that:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0f4fc15a\"><strong>Viscosity of A + Viscosity of B = Better Viscosity.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-bbe663b7\">Mixed polymers can show:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Synergistic viscosity increase<\/li>\n\n\n\n<li>Almost additive behavior<\/li>\n\n\n\n<li>Antagonistic thinning<\/li>\n\n\n\n<li>More elasticity<\/li>\n\n\n\n<li>Less elasticity<\/li>\n\n\n\n<li>Different recovery<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ba9d5c02\">The result depends on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Polymer concentration<\/li>\n\n\n\n<li>Charge density<\/li>\n\n\n\n<li>Molecular weight<\/li>\n\n\n\n<li>pH<\/li>\n\n\n\n<li>Electrolytes<\/li>\n\n\n\n<li>Binder \/ surfactants<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ef50d79b\">Therefore:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-19cb8340\"><strong>Never predict blend performance from the two individual water viscosities.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-7be8a5ee\">Total Polymer Solids Still Matter<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5057199e\">One advantage of acrylic pigment thickeners is that many grades work at relatively low dosage.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a318f5ec\">CMC and CMS are additional polymer solids.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-383de539\">If too much powder polymer is added to reduce acrylic cost, the blend can increase:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Total deposited solids<\/li>\n\n\n\n<li>Surface residue<\/li>\n\n\n\n<li>Fabric stiffness<\/li>\n\n\n\n<li>Preparation cost<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-29aa6910\">Calculate:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4b227b2d\"><strong>Total Thickener Polymer Solids = Acrylic Polymer Solids + CMC Solids + CMS Solids<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-32014574\">Then compare the final printed fabric.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b01e7444\">A lower raw-material cost per kilogram does not prove lower cost per printed meter.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-fe7f2bc0\">Low-Shear Body and Paste Hold<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-220845be\">One reason to test CMC or CMS is to change low-shear paste body without simply increasing acrylic dosage.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a3d3ef25\">Useful low-shear structure can improve:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Paste hold on screen<\/li>\n\n\n\n<li>Anti-sag behavior<\/li>\n\n\n\n<li>Controlled penetration<\/li>\n\n\n\n<li>Suspension<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d7edc608\">But excessive body can increase:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pumping resistance<\/li>\n\n\n\n<li>Screen-filling difficulty<\/li>\n\n\n\n<li>Heavy deposit<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e11fcb86\">The blend should therefore be tested across multiple shear conditions.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-21d4f22f\">Do not optimize low-shear viscosity independently from screen passage.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-d793d44b\">High-Shear Flow and Screen Passage<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-db009e84\">Acrylic thickeners are often selected because of useful shear-thinning behavior.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-be43a3c5\">Adding a polysaccharide component can change the flow curve.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2f527984\">The paste may become:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>More pseudoplastic<\/li>\n\n\n\n<li>Less shear thinning<\/li>\n\n\n\n<li>More resistant under squeegee shear<\/li>\n\n\n\n<li>More elastic<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9036505d\">depending on the polymers and ratio.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fffbf463\">Mixed-thickener research in textile printing demonstrates that polymer composition can change pseudoplastic behavior, add-on and penetration.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-abacfbf0\">For pigment printing, the important question is:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c958239e\"><strong>Does the compound paste pass the actual screen cleanly at the required deposit?<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-fe68f735\">Recovery, Leveling and Print Definition<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5da63d80\">After the squeegee or rotary screen applies high shear, the paste should recover enough structure to hold the printed pattern.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a29744d0\">If recovery is too slow:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Edges can spread.<\/li>\n\n\n\n<li>Penetration can increase.<\/li>\n\n\n\n<li>Fine detail can soften.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-779c8eac\">If recovery is too fast or elasticity is too high:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Leveling can suffer.<\/li>\n\n\n\n<li>Screen marks can remain.<\/li>\n\n\n\n<li>Stringing can increase.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-62f891b0\">CMC or CMS can shift recovery relative to an acrylic-only reference.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4dfeefd2\">The direction is grade- and ratio-specific.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-576991e8\">Measure it rather than assuming the blend improves recovery.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-bbf8f97b\">Water Retention and Penetration<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-68c8c2ef\">CMC and CMS can influence how water is held inside the paste.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8cb7052a\">This can affect:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fabric wetting<\/li>\n\n\n\n<li>Penetraci\u00f3n<\/li>\n\n\n\n<li>Surface pigment concentration<\/li>\n\n\n\n<li>Screen drying behavior<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-73f6aa1c\">Water retention can be useful when the acrylic-only paste penetrates too rapidly into an absorbent substrate.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a37a159a\">But excessive retention can also change:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Secado<\/li>\n\n\n\n<li>Leveling<\/li>\n\n\n\n<li>Binder-film development<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-019d408b\">Evaluate face-side color, reverse-side penetration and drying behavior together.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-95670b58\">Screenability and Filtration<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-032c94ff\">Powder polymers add another preparation and filtration variable.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0399cb06\">A compound paste should be checked for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Complete CMC \/ CMS hydration<\/li>\n\n\n\n<li>Part\u00edculas de gel<\/li>\n\n\n\n<li>Undissolved powder<\/li>\n\n\n\n<li>Residuo de filtraci\u00f3n<\/li>\n\n\n\n<li>Bloqueo de la pantalla<\/li>\n\n\n\n<li>Screen release<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-bfb5d33c\">An acrylic-only paste may be easier to prepare because the thickener is supplied as a liquid dispersion.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2548f09b\">A blended system only creates value if the additional hydration step does not increase machine interruptions or batch risk.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-e0a30631\">Binder Compatibility<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e98e45ee\">Pigment binder remains the main fixation component.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d9615191\">Compound thickener development must therefore keep binder compatibility at the center.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b274fd73\">Test whether CMC or CMS addition changes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Viscosidad<\/li>\n\n\n\n<li>pH<\/li>\n\n\n\n<li>Flocculation<\/li>\n\n\n\n<li>Gel formation<\/li>\n\n\n\n<li>Estabilidad de sujeci\u00f3n<\/li>\n\n\n\n<li>Binder-film distribution<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-00326202\">CMC and many acrylic thickeners are anionic, but that does not guarantee compatibility with every binder or auxiliary package.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4ad843be\">CMS compatibility is also grade-specific.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0e651e93\">Use the complete binder-containing paste for approval.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-3a2f9c27\">Pigment Dispersion and Surfactants<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5d11a5ca\">Pigment dispersion introduces:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pigment particles<\/li>\n\n\n\n<li>Agua<\/li>\n\n\n\n<li>Dispersant<\/li>\n\n\n\n<li>Surfactant<\/li>\n\n\n\n<li>Electrolytes<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1d9107b5\">These components can affect all parts of a compound system differently.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2de5bf1c\">Por ejemplo:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Surfactants may change HASE association.<\/li>\n\n\n\n<li>Electrolytes can change acrylic and CMC chain expansion.<\/li>\n\n\n\n<li>Pigment solids can change apparent viscosity through particle crowding.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9d0cd263\">This is why blend optimization must use the production pigment system.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-77918b43\">Electrolytes and Hard Water<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-df73348e\">CMC, CMS and anionic acrylic thickeners can all respond to ionic conditions.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d08994b8\">The magnitude and direction can differ.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-323df510\">Test the blend with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reference water<\/li>\n\n\n\n<li>Agua para las plantas<\/li>\n\n\n\n<li>Representative pigment \/ binder electrolyte load<\/li>\n\n\n\n<li>Fixer if

class=\"wp-block-list\">\n<li>Calcium<\/li>\n\n\n\n<li>Magnesium<\/li>\n\n\n\n<li>Conductividad<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-76c98db2\">A compound system that is stable in deionized water but unstable in plant water should not be approved.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-42b4a6bf\">pH and Acrylic Thickener Activation<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f0d68af6\">Many acrylic ASE\/HASE thickeners require controlled pH activation.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-77f07714\">CMC or CMS should not be allowed to make that activation step uncontrolled.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0976e42e\">Registro:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>pH before acrylic activation<\/li>\n\n\n\n<li>pH after activation<\/li>\n\n\n\n<li>pH after CMC \/ CMS addition<\/li>\n\n\n\n<li>Final paste pH<\/li>\n\n\n\n<li>Held pH<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-07196239\">If the blend changes the final pH, viscosity differences may come from acrylic activation rather than the secondary polymer itself.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c9899800\">Control pH before drawing conclusions about synergy.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-6332093b\">CMC \/ CMS Hydration Before Blending<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-10b1498e\">Powder-polysaccharide hydration is a major practical difference from liquid acrylic thickener.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9f9d7001\">Incomplete hydration can create:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lumps<\/li>\n\n\n\n<li>False low viscosity<\/li>\n\n\n\n<li>Delayed viscosity increase<\/li>\n\n\n\n<li>Filter residue<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c070b265\">Use a documented hydration method for the selected CMC or CMS grade.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e0b6743f\">Control:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Water quality<\/li>\n\n\n\n<li>Powder addition rate<\/li>\n\n\n\n<li>Mezcla<\/li>\n\n\n\n<li>Hora de hidratarse<\/li>\n\n\n\n<li>Temperature where relevant<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1244a412\">Do not compare blend ratios until the powder component is fully hydrated under a repeatable method.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-50274eb6\">Addition Order for a Compound Thickener<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3b188829\">There is no universal addition order for every acrylic + CMC\/CMS system.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8b234acf\">A controlled development program may compare:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pre-hydrated CMC \/ CMS added to an activated acrylic base<\/li>\n\n\n\n<li>Acrylic added into a prepared polysaccharide base<\/li>\n\n\n\n<li>Selected post-addition route where the commercial acrylic grade supports it<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-abf2f443\">For each route, record:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>pH<\/li>\n\n\n\n<li>Viscosidad<\/li>\n\n\n\n<li>Gel \/ lumps<\/li>\n\n\n\n<li>Mixing time<\/li>\n\n\n\n<li>Estabilidad de sujeci\u00f3n<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ee759104\">Choose the route that gives the most repeatable complete-paste behavior.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6236133a\">Do not select an order only because it is convenient in the laboratory.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-96d920b7\">Gel, Floc and Lumps in Mixed-Polymer Systems<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-cd50aaa1\">Compound systems create more opportunities for local concentration problems.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-34ebd4e5\">Possible causes of gel or lumps include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Incomplete CMC \/ CMS hydration<\/li>\n\n\n\n<li>Local acrylic over-neutralization<\/li>\n\n\n\n<li>Electrolyte shock<\/li>\n\n\n\n<li>Cationic fixer interaction<\/li>\n\n\n\n<li>Poor mixing<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1c223c7c\">If gel appears, identify the first stage where it forms.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8a7c28c8\">Do not assume:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f781f218\"><strong>\u201cCMC and acrylic are chemically incompatible.\u201d<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6c031a9d\">The actual cause can be preparation sequence or local pH.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-bd481810\">Fabric Hand and Residual Polymer Solids<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1c52d704\">Pigment printing already leaves a binder film on the textile.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b122467a\">CMC and CMS add more nonvolatile polymer.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9c772828\">If the blend requires too much polysaccharide to reach the target rheology, printed-area hand can become:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heavier<\/li>\n\n\n\n<li>Stiffer<\/li>\n\n\n\n<li>More coated<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-127829cc\">Compare hand at matched:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Color \/ opacity<\/li>\n\n\n\n<li>Paste add-on<\/li>\n\n\n\n<li>Resistencia al roce<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-037f2083\">Do not compare a thin acrylic-only print with a much heavier compound-paste deposit and attribute the entire hand difference to polymer chemistry.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-9ae78736\">Rubbing Fastness: Thickener Is Not the Binder<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d6eccb54\">CMC and CMS are rheology-control components.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2f81fefe\">They do not replace the dedicated pigment binder.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c8fb2b45\">If dry or wet rubbing falls after blending, first investigate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Binder-to-pigment ratio<\/li>\n\n\n\n<li>Binder distribution<\/li>\n\n\n\n<li>Paste add-on<\/li>\n\n\n\n<li>Curado<\/li>\n\n\n\n<li>Thickener \/ binder compatibility<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-418d2ba3\">Do not correct poor rubbing by simply increasing CMC or CMS.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c58d3bee\">The blend should improve rheology without disrupting binder-film performance.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-3e54ba8f\">Curing and Binder Film Formation<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-56e47f2f\">After the compound paste is printed, binder must still form a continuous durable film.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-42630bc4\">Validate the blend under the same:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Condiciones de secado<\/li>\n\n\n\n<li>Curing temperature<\/li>\n\n\n\n<li>Curing time<\/li>\n\n\n\n<li>Fabric conditions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-790fa2cb\">used for the acrylic-only reference.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c518c3ab\">If the compound system changes water retention or deposit, drying and curing may also need review.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-43e6c169\">Do not assume the same thermal response without a production-relevant trial.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-8acdbc66\">Post-Cure Cleaning and Residue<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-57b3494a\">Conventional pigment printing should not be treated like reactive printing wash-off.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c4d40bab\">The binder film is intended to remain.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a4fabd38\">However, CMC or CMS addition can change:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Surface residue<\/li>\n\n\n\n<li>Post-cure washing behavior where washing is used<\/li>\n\n\n\n<li>Hand<\/li>\n\n\n\n<li>Screen \/ equipment cleaning<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c7ca2df2\">If the process includes post-cure washing, compare the actual customer process.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b3786b3e\">Do not claim that one blend is \u201ceasy wash-off\u201d without a defined procedure and finished-fabric test.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-65429911\">When Can a Compound System Improve Total Cost in Use?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-10089e03\">A compound system can create economic value if the lower acrylic dosage or improved rheology offsets the added:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CMC \/ CMS cost<\/li>\n\n\n\n<li>Hora de hidratarse<\/li>\n\n\n\n<li>Mixing energy<\/li>\n\n\n\n<li>Filtraci\u00f3n<\/li>\n\n\n\n<li>QC complexity<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a89e52ac\">A useful model is:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-df9b1a1c\"><strong>Total Cost in Use = Acrylic + CMC\/CMS + Preparation + Mixing + Filtration + Machine Efficiency + Curing + Rework + Quality Loss<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-aa7c88a5\">The blend should be adopted only if it reduces the cost of producing an acceptable printed meter.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-493008cd\">Raw-material price per kilogram is not enough.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-552f8128\">Build a Controlled Blend-Ratio Ladder<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-41479816\">Start with the acrylic-only formula as the reference.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-88378d87\">Then create several defined partial-substitution levels.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fd6b328a\">For example, a laboratory design can use:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reference:<\/strong> acrylic-only<\/li>\n\n\n\n<li><strong>Low blend:<\/strong> small CMC or CMS contribution<\/li>\n\n\n\n<li><strong>Medium blend:<\/strong> larger secondary-polymer contribution<\/li>\n\n\n\n<li><strong>High blend:<\/strong> stress point for technical understanding<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-46ec5f68\">The exact percentages should be chosen for the commercial grade and target problem.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-dd1dba7e\">Do not assume a universal 90\/10, 80\/20 or 70\/30 ratio is appropriate for every formula.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e41cb815\">At each point, keep pigment, binder and auxiliaries constant first.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-9dcc84bd\">Compare on Both Product and Polymer-Solids Basis<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a7bd4d41\">Liquid acrylic thickener and dry CMC\/CMS have very different product solids.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-dd0d7d8b\">Therefore, comparing only product kilograms can be misleading.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph

Blending Only to Reduce Raw-Material Price<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8d71fafb\">Lower raw-material cost can be lost through higher dosage, preparation or printing defects.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-0f522dd7\">2. Treating CMC or CMS as a Weight-for-Weight Acrylic Replacement<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a2512d8d\">The polymers have different solids, rheology and preparation behavior.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-5453a772\">3. Comparing Water Viscosity Only<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-278f5c1f\">Pigment, binder, electrolyte and shear can change the blend strongly.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-287981f0\">4.

Can acrylic thickener be blended with CMC for pigment printing?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7643fe19\">Yes, in selected formulations. CMC can be evaluated as a supporting rheology component for body, water retention or penetration control, but the complete pigment\/binder system must be tested.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-6d97925e\">2. Can acrylic thickener be blended with CMS?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f8f5389c\">Yes, selected CMS grades can be evaluated in compound systems for viscosity, body, water retention, suspension or cost-performance adjustment. Grade selection and hydration are important.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-8ae25eb0\">3. Is CMC better than CMS for a compound pigment thickener?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5387370f\">Neither is universally better. CMC and CMS have different polymer structures, hydration, film and electrolyte behavior. Select according to the weakness that needs correction.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-bab53793\">4. Can CMC or CMS directly replace acrylic thickener by weight?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c20a9a69\">Not as a general rule. Their product solids, required dosage, rheology and preparation are different. Use a controlled partial-substitution matrix.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-68b49151\">5. Why can a blend have lower viscosity than either thickener alone?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0cabf462\">Polymer interactions, pH, electrolytes, dilution and associative effects can create antagonistic rheology. Mixed-polymer viscosity is not always additive.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-11ec87c8\">6. Does adding CMC or CMS always reduce cost?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-07a41d1d\">No. Include dosage, hydration, mixing, filtration, machine efficiency, rejects and hand in Total Cost in Use.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-d74efc60\">7. Can a compound thickener improve fabric hand?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-42393d33\">Potentially, if it allows a lower total polymer deposit or better paste add-on. But excessive CMC\/CMS solids can also make the print heavier or stiffer.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-dde1336d\">8. Why does a compound paste form lumps?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-802c994b\">Common causes include incomplete CMC\/CMS hydration, local acrylic over-neutralization, poor addition order, electrolyte shock or cationic fixer interaction.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-9dd3045d\">9. Should I compare blend ratios by product weight or active solids?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-13621b6e\">Record both. Product-weight comparison is practical for production, while active-polymer solids help explain rheology efficiency and hand.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-b64c44d8\">10. Does CMC or CMS improve rubbing fastness?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-00cc6c23\">They are not the main pigment binder. Any fastness change should be evaluated through binder distribution, curing and complete-paste compatibility.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-362c6388\">11. What is the best first blend ratio?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8e558640\">There is no universal ratio. Start from the acrylic-only reference and introduce the secondary polymer in controlled partial-substitution steps appropriate to the actual commercial grades.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-987c9588\">12. What should I send FSX Chemical for compound-thickener matching?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0a95ac83\">Send the current acrylic thickener, CMC\/CMS data, pigment, binder, fixer, full or simplified formula, viscosity method, water quality, fabric, screen route, holding time and the specific performance or cost target.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-e22eb891\">Develop a Compound Thickener Only When Each Polymer Has a Clear Job<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2a59adc1\">If your acrylic pigment-printing thickener gives acceptable results but you want to adjust paste body, penetration, water retention, working dosage or Total Cost in Use, FSX Chemical can help structure a controlled acrylic + CMC or acrylic + CMS trial.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-19009797\">For a useful technical review, send:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your current acrylic thickener sample, TDS or COA<\/li>\n\n\n\n<li>Current acrylic dosage<\/li>\n\n\n\n<li>CMC or CMS grade \/ TDS if already selected<\/li>\n\n\n\n<li>Pigment product and dosage<\/li>\n\n\n\n<li>Binder grade and dosage<\/li>\n\n\n\n<li>Fixer \/ auxiliary package<\/li>\n\n\n\n<li>Final paste pH<\/li>\n\n\n\n<li>M\u00e9todo completo de ensayo de viscosidad<\/li>\n\n\n\n<li>Water hardness \/ conductivity<\/li>\n\n\n\n<li>Fabric and screen route<\/li>\n\n\n\n<li>Tiempo de retenci\u00f3n<\/li>\n\n\n\n<li>Your current technical or cost target<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-96a0dcb1\">Empieza con <a href=\"https:\/\/fsxchemical.com\/es\/servicio\/muestras-coincidentes\/\">Muestras y combinaci\u00f3n<\/a> for a controlled compound-thickener comparison.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9cbaaafe\">Rese\u00f1a <a href=\"https:\/\/fsxchemical.com\/es\/producto\/synthetic-printing\/\">Synthetic Printing Thickeners<\/a>, <a href=\"https:\/\/fsxchemical.com\/es\/producto\/carboximetilcelulosa-cmc\/\">CMC<\/a> y <a href=\"https:\/\/fsxchemical.com\/es\/producto\/almidon-carboximetilico-cms\/\">CMS<\/a> for the current FSX product routes.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-00100e68\">Tambi\u00e9n puedes <a href=\"https:\/\/fsxchemical.com\/es\/servicio\/solicitar-una-cotizacion\/\">Solicita una cotizaci\u00f3n directamente del fabricante<\/a> after the suitable compound system and working dosage are confirmed or <a href=\"https:\/\/fsxchemical.com\/es\/contactanos\/\">P\u00f3ngase en contacto con FSX Chemical<\/a> para conversaciones t\u00e9cnicas\ud83d\udce7\u00a0<strong>Correo electr\u00f3nico<a href=\"https:\/\/fsxchemical.com\/es\/contactanos\/\">: Service@fsxchemical.com<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0ad17ffc\"><strong>A successful compound thickener is not the formula with the highest CMC or CMS replacement percentage.
