Using high-grade pigment pastes is essential to produce premium solid surface products. Compared to powder pigments (which tend to lump, <strong>slow down cycle mixing times, and reduce color yield), liquid pigment dispersions facilitate rapid, clean dispersion, guaranteeing flawless colour distribution without disrupting resin catalysis.<\/strong> At AITANACHEM, we supply <strong>high-concentration reactive pigment pastes specifically engineered for solid surface production<\/strong>, and we provide technical assistance on the most delicate aspect of the process: colour.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d6812bf elementor-widget elementor-widget-image\" data-id=\"d6812bf\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"599\" height=\"801\" src=\"https:\/\/aitanachem.com\/wp-content\/uploads\/2022\/01\/pastas-pigmentarias.webp\" class=\"attachment-medium_large size-medium_large wp-image-749\" alt=\"pigment-pastes\" srcset=\"https:\/\/aitanachem.com\/wp-content\/uploads\/2022\/01\/pastas-pigmentarias.webp 599w, https:\/\/aitanachem.com\/wp-content\/uploads\/2022\/01\/pastas-pigmentarias-224x300.webp 224w\" sizes=\"(max-width: 599px) 100vw, 599px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ce587fd elementor-widget elementor-widget-heading\" data-id=\"ce587fd\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What Is a Pigment Paste?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f2a5167 elementor-widget elementor-widget-text-editor\" data-id=\"f2a5167\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>A pigment paste is a <strong>stable dispersion containing a high concentration of solid pigments (organic or inorganic) suspended in a liquid carrier (a resin) compatible with the target polyester matrix.<\/strong> Compared to solid powder pigments, paste integrates far better into the mixture (yielding homogeneous coloration) and offers higher tinting strength.

At AITANACHEM, we formulate and supply pigment pastes adhering to strict technical specifications to guarantee maximum end-product quality:<\/p>\n<ul>\n<li><strong>High Tinting Strength and Hide Power:<\/strong> Formulated with an elevated pigment concentration (at least 70%) to reach the desired saturation level using the lowest possible paste ratio in the formulation.<\/li>\n<li><strong>Catalysis System Compatibility:<\/strong> Free of unreacted substances or cheap extender fillers (such as uncontrolled carbonates) that can unpredictably inhibit or accelerate polymerization and alter gel times. Extender fillers accompany the pigment to adjust properties or lower costs, sometimes accounting for 30\u201350% of the paste&#8217;s composition. <strong>Due to rising TiO\u2082 (titanium dioxide) prices, substituting it with cheaper carbonates or ultra-white marble dust is common<\/strong>; while this maintains price points, it can weaken the finished part against household acids.<\/li>\n<li><strong>Free of Styrene and Harmful Additives:<\/strong> Formulated without styrene or additives that impair catalyst breakdown or slurry reactivity.<\/li>\n<li><strong>Chemical and Thermal Resistance:<\/strong> Selected pigments withstand high peak exotherms during curing and resist continuous contact with household cleaners, detergents, mild acids, and alkalis.<\/li>\n<li><strong>UV Stability (Anti-Yellowing):<\/strong> Doped with thermal and light stabilizers to prevent colour degradation and premature aging when exposed to natural or artificial light.<\/li>\n<li><strong>Single-Pigment Formulations:<\/strong> We recommend selecting single-pigment shades whenever feasible, significantly reducing the risk of colour separation caused by fluid dynamics during mould filling.<\/li>\n<\/ul>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-30dbd9c elementor-widget elementor-widget-heading\" data-id=\"30dbd9c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">How to Prevent Color Separation and Marbling in the Mould<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-cc4cb82 elementor-widget elementor-widget-text-editor\" data-id=\"cc4cb82\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>During open mould filling or pressure injection, the moving mixture stream contacts the mould walls and intersecting flow fronts.
