The paste may contain a large amount of suspended pigment solids, higher binder demand, more dispersant and surfactant, and a heavier nonvolatile deposit on the fabric. Opaque white pastes often rely on high levels of white opacifying pigment such as titanium dioxide, so rheology must balance yield stress, shear thinning, screen passage, leveling and recovery rather than simply maximize viscosity. The best acrylic thickener is therefore the grade that keeps a high-solids paste pumpable and screenable while maintaining opacity, clean transfer and an acceptable fabric hand at the lowest practical polymer dosage.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-85e268e6\">What Changes in High-Pigment and White Printing Pastes?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-30d3de8c\">The main difference is the total solids burden placed on the rheology system.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a32b51f4\">Compared with a normal pigment shade, a high-pigment or opaque white paste can contain more:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u0627\u0644\u0645\u0648\u0627\u062f \u0627\u0644\u0635\u0628\u063a\u064a\u0629

rises, the acrylic thickener must control not only water but also a denser suspension of solid particles.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fcdc672a\">The useful rheology therefore becomes:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-93b16481\"><strong>Low-Shear Stability \u2192 Shear Thinning \u2192 Screen Passage \u2192 Controlled Recovery \u2192 Leveling \u2192 Stable

printing is designed to hide the underlying fabric color.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0db44afd\">On dark fabrics, that requires enough:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>White pigment concentration<\/li>\n\n\n\n<li>Optical hiding power<\/li>\n\n\n\n<li>Uniform surface coverage<\/li>\n\n\n\n<li>\u063a\u0634\u0627\u0621 \u0627\u0644\u062a\u063a\u0644\u064a\u0641<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a7a16d9c\">Commercial opaque whites therefore tend to carry a higher pigment and binder burden than transparent or light-shade pastes.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ef6d03da\">This creates a more difficult balance between:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Opacity<\/li>\n\n\n\n<li>\u0642\u0627\u0628\u0644\u064a\u0629

class=\"wp-block-wd-paragraph wd-441ef3ce\">A thick paste can improve surface hold but become difficult to pass through the screen.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a8faaa29\">A fluid paste can screen easily but lose opacity through excessive penetration or uneven deposit.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-5c5db35d\">Why Titanium Dioxide Changes the Rheology Problem<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5f120f26\">Titanium dioxide is widely used as an opacifying white pigment because of its high light-scattering and hiding ability.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5fe6076c\">Not every commercial white paste uses exactly the same pigment package, but high-opacity textile whites commonly rely heavily on TiO<sub>2<\/sub>.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7a76a4b8\">Compared with a normal colored pigment formula, a high TiO<sub>2<\/sub> paste can introduce:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>High suspended-solids volume<\/li>\n\n\n\n<li>Strong particle-particle interactions<\/li>\n\n\n\n<li>Higher dispersant demand<\/li>\n\n\n\n<li>Higher binder demand<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d1d77398\">The rheology system must therefore support a particle-rich suspension without becoming excessively elastic, pasty or difficult to screen.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-02e970a4\">This is why white-paste thickener selection should be performed in the actual white pigment \/ binder system.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-ecc8ce22\">High Solids, Particle Crowding and Yield Stress<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6a9c1aef\">As pigment solids increase, particles occupy more of the liquid volume.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-06b05414\">At sufficiently high solids, particle crowding can increase resistance to flow.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-22c26249\">This can raise:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Apparent viscosity<\/li>\n\n\n\n<li>\u0625\u062c\u0647\u0627\u062f \u0627\u0644\u062e\u0636\u0648\u0639<\/li>\n\n\n\n<li>Mixing torque<\/li>\n\n\n\n<li>Pumping demand<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8d241311\">At the same time, surfactants and electrolytes introduced with the pigment dispersion can reduce acrylic-thickener efficiency.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-20a3ce25\">The final effect can therefore be nonlinear.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4d7da8bf\">High pigment loading can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Increase viscosity through particle crowding<\/li>\n\n\n\n<li>Reduce viscosity through dilution or electrolyte effects<\/li>\n\n\n\n<li>Leave low-shear viscosity similar while changing high-shear behavior<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-f7c45e92\">Measure the actual complete paste rather than predicting from pigment percentage.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title

class=\"wp-block-wd-paragraph wd-cd12c8e9\">High-pigment paste can have the correct Brookfield viscosity but still print poorly.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-998e802f\">Possible reasons include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Too much yield stress<\/li>\n\n\n\n<li>Insufficient shear thinning<\/li>\n\n\n\n<li>Slow screen release<\/li>\n\n\n\n<li>Excess elasticity<\/li>\n\n\n\n<li>\u062a\u0633\u0648\u064a\u0629 \u063a\u064a\u0631 \u062c\u064a\u062f\u0629<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-dbbeaa99\">Screen-printing research consistently shows that viscosity, thixotropy, yield behavior and viscoelasticity together influence printing performance.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2cfc2c68\">For white paste, the correct question is:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c1dd23c0\"><strong>Does the paste flow through the screen, deposit enough opaque material, recover without spreading and level without leaving severe screen texture?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-76ec9f43\">That cannot be answered by one low-shear number alone.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-0ac20d35\">Low-Shear Body: Preventing Settling and Flow-Out<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ec0df7a1\">High pigment loading requires enough low-shear structure to keep the paste stable at rest.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-933109ff\">Useful low-shear body helps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduce pigment settling<\/li>\n\n\n\n<li>Maintain paste on the screen<\/li>\n\n\n\n<li>Limit uncontrolled flow-out after printing<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3c57f89c\">But excessive low-shear structure can create:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u0635\u0639\u0648\u0628\u0629 \u0641\u064a \u0627\u0644\u0636\u062e<\/li>\n\n\n\n<li>\u0645\u0644\u0621

class=\"wp-block-wd-paragraph wd-10074124\">The goal is not maximum yield stress.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c534589b\">The goal is:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4434a469\"><strong>Enough structure for suspension and hold, but low enough resistance for clean screen transfer.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-32f66cbe\">Shear Thinning: Getting High-Solids Paste Through the Screen<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-89db0e26\">During screen passage, the paste experiences much higher shear.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3815d6eb\">A good acrylic thickener should allow:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-05650fbe\"><strong>High-Solids Paste + High Shear \u2192 Lower Apparent Viscosity \u2192 Efficient Screen Passage<\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6277030c\">without losing the ability to recover after transfer.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-fceea984\">This shear-thinning behavior is especially important for white paste because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The particle load is high.<\/li>\n\n\n\n<li>The screen may be relatively open to allow adequate deposit.<\/li>\n\n\n\n<li>The paste can otherwise require excessive printing pressure.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-6905e16c\">If shear thinning is insufficient, the operator may compensate with higher squeegee pressure, which can increase penetration and hand problems.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-6d9391cc\">Recovery: Holding the White Deposit After Transfer<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-4e9f4006\">After the paste leaves the screen, shear drops rapidly.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-22d93d1a\">The thickener should rebuild enough structure to hold the deposited pigment near the fabric surface.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-ffa052c5\">If recovery is too slow:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>White paste can spread.<\/li>\n\n\n\n<li>Edges can lose definition.<\/li>\n\n\n\n<li>More pigment can penetrate into the fabric.<\/li>\n\n\n\n<li>Surface opacity can fall.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-373060ed\">If recovery is too fast:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Leveling can suffer.<\/li>\n\n\n\n<li>Mesh marks can remain visible.<\/li>\n\n\n\n<li>Surface texture can become rough.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-24a015a5\">White-paste rheology therefore requires controlled recovery, not maximum recovery speed.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-aa7d9ec5\">Leveling vs. Mesh Marks<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-32c74567\">Opaque white pastes often deposit a relatively thick visible layer.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d6066008\">This makes surface texture easy to see.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d6b16347\">Poor leveling can leave:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mesh pattern<\/li>\n\n\n\n<li>Ridges<\/li>\n\n\n\n<li>Uneven surface gloss<\/li>\n\n\n\n<li>Patchy opacity<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-06bf0837\">Too much leveling, however, can increase:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u0627\u0644\u0627\u0646\u062a\u0634\u0627\u0631<\/li>\n\n\n\n<li>Edge

transfer to smooth the surface without allowing the white deposit to move excessively.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-c73ae9f7\">What Does Good Screenability Mean for White Paste?<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-00104bf2\">Good screenability means the paste can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fill the screen consistently<\/li>\n\n\n\n<li>Pass through the openings under normal printing pressure<\/li>\n\n\n\n<li>Release cleanly<\/li>\n\n\n\n<li>Maintain deposit consistency<\/li>\n\n\n\n<li>Avoid rapid blockage<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5396bdb5\">For high-pigment paste, also monitor:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Particle \/ gel residue<\/li>\n\n\n\n<li>Drying at the screen<\/li>\n\n\n\n<li>Beginning-to-end deposit<\/li>\n\n\n\n<li>Cleaning frequency<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c38d3130\">A paste with excellent opacity but poor running stability is not a production-ready formula.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-f0708037\">Screen Mesh, Engraving and Open Area<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b0cf0a2c\">White opacity often depends partly on the amount of paste deposited.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-bc4e53ef\">Screen geometry therefore matters greatly.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-02be06c5\">Larger openings or deeper engraving can increase deposit, but may also increase:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Paste consumption<\/li>\n\n\n\n<li>\u0627\u0644\u064a\u062f<\/li>\n\n\n\n<li>Drying load<\/li>\n\n\n\n<li>Risk of edge buildup<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9d001de8\">Finer screens can improve detail but may be difficult for a highly loaded paste.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-a28b87f4\">\u0644\u0630\u0644\u0643:<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-38701f40\"><strong>Thickener Rheology + Screen Geometry + Opacity Target<\/strong><\/p>\n\n\n\n<p

class=\"wp-block-wd-paragraph wd-0bce189b\">Higher pressure or more strokes can increase white-paste add-on.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c18afa7f\">This can improve apparent opacity but also increase:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u0627\u0644\u0627\u062e\u062a\u0631\u0627\u0642<\/li>\n\n\n\n<li>Polymer deposit<\/li>\n\n\n\n<li>Printed-area

pigment mass.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-244c0d7d\">But total deposit should be distinguished from formula concentration.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph

paste can still produce a lighter hand if rheology allows lower add-on at the same opacity.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-7984028d\">Record paste add-on whenever possible.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-3a3bd498\">Opacity vs. Rheology: Why More Deposit Is Not Always Better<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d09da0e8\">Higher white-paste deposit can increase hiding power up to the useful application range.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-93c40ea4\">But beyond that point, additional deposit can create diminishing benefits and increasing penalties:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Harder hand<\/li>\n\n\n\n<li>Slower drying<\/li>\n\n\n\n<li>Higher binder demand<\/li>\n\n\n\n<li>More

class=\"wp-block-wd-title title wd-268088b8\">1. Why is white pigment paste harder to thicken than normal pigment paste?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-8afecc23\">Opaque white paste often contains a much higher suspended-pigment load, more dispersant and often more binder, creating a high-solids system with stronger particle interactions.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-0252f6eb\">2. Is titanium dioxide always used in white textile pigment printing?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-0fb2d921\">TiO2 is one of the most common opacifying white pigments because of its hiding power, but commercial white systems can use different or combined opacifying pigments.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-98b31236\">3. Does white paste need a higher Brookfield viscosity?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c427776e\">Not necessarily. It needs enough low-shear structure for suspension and hold, but also sufficient shear thinning for clean screen passage and leveling.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-2adfc2af\">4. Why does white paste become too difficult to screen?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-d159092b\">Possible causes include excessive yield stress, high thickener dosage, particle crowding, insufficient shear thinning, screen geometry or binder\/thickener interaction.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-f937eb70\">5. Why does white paste settle even when viscosity looks high?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-97f4601e\">Suspension stability depends on low-shear yield behavior, particle dispersion and structure\u2014not only one viscosity reading.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-7d641d18\">6. Why does more white paste improve opacity but make the print hard?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5ebc5264\">Higher add-on deposits more pigment, binder and thickener solids, increasing film mass and stiffness.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-f6668b13\">7. How can I improve opacity without making the print much harder?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1c552d9d\">Optimize pigment dispersion, screen deposit, leveling, thickener efficiency and binder minimum so the required hiding power is achieved at the lowest practical deposit.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-f38a2180\">8. Why does white paste show mesh marks?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-e909d773\">The paste may recover too quickly or level too slowly after transfer, or the deposit may be too heavy for the current screen\/rheology combination.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-2b490a3c\">9. Why do pinholes appear in opaque white printing?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-9f3b34ab\">Possible causes include microfoam, poor screen filling, uneven pigment dispersion or insufficient leveling.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-bd6a4433\">10. Should binder be increased when white pigment loading increases?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-5f23b105\">Binder demand may increase, but the correct level should be determined from pigment\/binder ratio, rubbing fastness, hand and curing\u2014not pigment percentage alone.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-160a4e3e\">11. What should be checked besides viscosity?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-1241681a\">Check yield behavior, shear thinning, recovery, screenability, add-on, opacity, rubbing fastness, holding stability and fabric hand.<\/p>\n\n\n\n<h3 class=\"wp-block-wd-title title wd-59f30d23\">12. What should I send FSX Chemical for white-paste matching?<\/h3>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-c67203eb\">Send the white pigment product and dosage, thickener, binder, pH, viscosity method, screen, add-on if known, fabric, curing conditions and the main opacity, screenability or hand problem.<\/p>\n\n\n\n<h2 class=\"wp-block-wd-title title wd-9134bd84\">Match Acrylic Thickener to High-Pigment and Opaque White Pastes<\/h2>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-b3d0a8f2\">If your white or high-pigment paste gives good opacity but poor screenability, settles during holding, shows mesh marks, creates a hard hand or requires excessive thickener dosage, FSX Chemical can help structure a controlled high-solids rheology trial.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-af5a53e2\">For a useful technical review, send:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your white \/ high-pigment dispersion product and dosage<\/li>\n\n\n\n<li>Pigment solids if available<\/li>\n\n\n\n<li>Your current acrylic thickener sample, TDS or COA<\/li>\n\n\n\n<li>\u062c\u0631\u0639\u0629 \u0627\u0644\u0645\u064f\u0643\u062b\u0650\u0651\u0641<\/li>\n\n\n\n<li>Binder grade \/ dosage \/ solids<\/li>\n\n\n\n<li>Fixer \/ auxiliary system<\/li>\n\n\n\n<li>Final paste pH and viscosity test method<\/li>\n\n\n\n<li>\u0634\u0628\u0643\u0629 \u0627\u0644\u0634\u0627\u0634\u0629 \/ \u0627\u0644\u0646\u0642\u0634<\/li>\n\n\n\n<li>Squeegee pressure \/ speed \/ strokes<\/li>\n\n\n\n<li>Paste add-on if available<\/li>\n\n\n\n<li>Fabric type and color<\/li>\n\n\n\n<li>Curing conditions<\/li>\n\n\n\n<li>Current issue: opacity, screenability, settling, hand or rubbing<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-3cac5507\">\u0627\u0628\u062f\u0623 \u0628\u0640 <a href=\"https:\/\/fsxchemical.com\/ar\/%d8%a7%d9%84%d8%ae%d8%af%d9%85%d8%a9\/%d9%85%d8%b7%d8%a7%d8%a8%d9%82%d8%a9-%d8%a7%d9%84%d8%b9%d9%8a%d9%86%d8%a7%d8%aa\/\">\u0627\u0644\u0639\u064a\u0646\u0627\u062a \u0648\u0627\u0644\u0645\u0637\u0627\u0628\u0642\u0629<\/a> for a controlled current-vs-candidate evaluation.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-17eccc1f\">\u0645\u0631\u0627\u062c\u0639\u0629 <a href=\"https:\/\/fsxchemical.com\/ar\/product\/synthetic-printing\/\">Synthetic Printing Thickeners<\/a> for the current FSX pigment-printing thickener range.<\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-14d24725\">You can also <a href=\"https:\/\/fsxchemical.com\/ar\/%d8%a7%d9%84%d8%ae%d8%af%d9%85%d8%a9\/%d8%b7%d9%84%d8%a8-%d8%b9%d8%b1%d8%b6-%d8%a3%d8%b3%d8%b9%d8%a7%d8%b1\/\">\u0627\u0637\u0644\u0628 \u0639\u0631\u0636 \u0623\u0633\u0639\u0627\u0631 \u0645\u0628\u0627\u0634\u0631 \u0645\u0646 \u0627\u0644\u0645\u0635\u0646\u0639<\/a> after the suitable high-pigment working window is confirmed or <a href=\"https:\/\/fsxchemical.com\/ar\/%d8%a7%d8%aa%d8%b5%d9%84-%d8%a8%d9%86%d8%a7\/\">\u0627\u062a\u0635\u0644 \u0628\u0634\u0631\u0643\u0629 FSX Chemical<\/a> for technical discussion\ud83d\udce7\u00a0<strong>\u0627\u0644\u0628\u0631\u064a\u062f \u0627\u0644\u0625\u0644\u0643\u062a\u0631\u0648\u0646\u064a<a href=\"https:\/\/fsxchemical.com\/ar\/%d8%a7%d8%aa%d8%b5%d9%84-%d8%a8%d9%86%d8%a7\/\">: Service@fsxchemical.com<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-wd-paragraph wd-2883dfdd\"><strong>A good white-paste thickener does not simply make the paste thick.
