A useful supplier discussion should connect rutile or anatase grade selection, surface treatment, particle size, oil absorption, and processing conditions to the customer&#8217;s finished product target.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Longtai writes this guide from a manufacturer and chemical application perspective. If you are reviewing titanium dioxide for high-solids coatings, the important question is whether the material can meet your quality standard in production, including the same resin, binder, filler package, temperature, shear level, and final inspection method used by your plant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For faster technical support, share your application, current material issue, target whiteness or shade, processing method, dosage range, and required documents such as TDS, SDS, or COA. Longtai can then recommend a focused sample direction from the relevant <a href=\"https:\/\/www.hnlongtai.com\/zh\/%e4%ba%a7%e5%93%81%e7%b1%bb%e5%88%ab\/titanium-dioxide\/\">\u4e8c\u6c27\u5316\u949b\u4ea7\u54c1\u8303\u56f4<\/a>.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"why\">Why viscosity and hiding-power tradeoffs changes pigment performance<\/h2>\n<p class=\"wp-block-paragraph\">High-solids coatings contain less solvent or water to separate particles and dissipate mixing energy. Pigment surface area, surface treatment, binder functionality, and dispersant efficiency therefore have a larger effect on flow and usable application solids.<\/p>\n<p class=\"wp-block-paragraph\">For this reason, titanium dioxide for high-solids coatings should be treated as a formulation-and-process decision. A grade with excellent tint strength can force excessive solvent addition or produce poor atomization, sag balance, and leveling. Comparing only equal-weight formulas hides the value of a pigment that permits higher application solids. The useful question is not whether one certificate number is higher, but whether the candidate creates a stable, reproducible coating within the plant&#8217;s operating limits.<\/p>\n<figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/www.hnlongtai.com\/wp-content\/uploads\/2026\/07\/titanium-dioxide-particle-size-distribution-coatings.png\" alt=\"titanium dioxide for high-solids coatings laboratory comparison with pigment distribution curves and coating drawdowns\" class=\"wp-image-3626\" srcset=\"https:\/\/www.hnlongtai.com\/wp-content\/uploads\/2026\/07\/titanium-dioxide-particle-size-distribution-coatings.png 1536w, https:\/\/www.hnlongtai.com\/wp-content\/uploads\/2026\/07\/titanium-dioxide-particle-size-distribution-coatings-300x200.png 300w, https:\/\/www.hnlongtai.com\/wp-content\/uploads\/2026\/07\/titanium-dioxide-particle-size-distribution-coatings-1024x683.png 1024w, https:\/\/www.hnlongtai.com\/wp-content\/uploads\/2026\/07\/titanium-dioxide-particle-size-distribution-coatings-768x512.png 768w, https:\/\/www.hnlongtai.com\/wp-content\/uploads\/2026\/07\/titanium-dioxide-particle-size-distribution-coatings-18x12.png 18w, https:\/\/www.hnlongtai.com\/wp-content\/uploads\/2026\/07\/titanium-dioxide-particle-size-distribution-coatings-600x400.png 600w\" sizes=\"(max-width: 1536px) 100vw, 1536px\" \/><\/figure>\n<h2 class=\"wp-block-heading\" id=\"compare\">What to compare before approving titanium dioxide for high-solids coatings<\/h2>\n<p class=\"wp-block-paragraph\">Compare viscosity at matched solids and matched application viscosity, then measure contrast ratio, gloss, sag, leveling, volatile content, and cured-film properties.

Dilution may mask the cause while reducing compliant solids, film build, and transfer efficiency. Change one variable at a time and preserve the original control. Otherwise, simultaneous changes to dispersant, shear, binder, and pigment loading make the cause impossible to identify.<\/p>\n<h3 class=\"wp-block-heading\">\u4e0e\u5149\u5b66\u62e5\u6324\u5206\u5f00\u5206\u6563<\/h3>\n<p class=\"wp-block-paragraph\">If fineness improves but hiding does not, check film thickness, pigment volume concentration, extender spacing, and refractive-index contrast. If tint strength or gloss changes after a rub-up or after letdown, investigate flocculation. This distinction keeps a titanium dioxide for high-solids coatings project from becoming an endless increase in milling time.<\/p>\n<h3 class=\"wp-block-heading\">\u8ba1\u7b97\u4ea4\u4ed8\u4ef7\u503c<\/h3>\n<p class=\"wp-block-paragraph\">Compare cost at the dosage that actually passes, including dispersion time, yield loss, solvent or water adjustment, and rework risk. The cheapest price per tonne is not necessarily the lowest cost per passing litre of paint.
