WT Water-Soluble, Resin-Free Color Paste Series

Overview

TheWT seriesis a pure waterborne, resin-free pigment paste line engineered for water-based coating systems. It disperses cleanly in bothPure Water Formulationsandwater/solvent co-solvent systems, delivering strong chemical resistance, broad binder compatibility, and stable color development.

Grades with a"T" suffixUses nano-scale particles for high transparency, excellent heat resistance, and superior lightfastness. The entire product line is eco-friendly and non-toxic.

Key Features

• Pure waterborne and resin-free— No free resin, maximum formulation flexibility
• Dual-system compatibility— Works in pure water and water/solvent co-solvent systems
• High chemical resistance— Stable in demanding coating environments
• Nano-transparent T-grades— Ultra-fine particle size for transparent, clean shades
• High heat resistance— up to 240°C for most grades
• Excellent lightfastness— up to grade 8 (Blue Wool scale)
• Migration resistance level 5— no bleeding or color transfer
• Eco-friendly & non-toxic— Low VOC, compliant with modern environmental standards

Usage Recommendations

For optimal gloss and compatibility, pre-dilute the color paste with deionized water at a1:1 or 1:2 aspect ratio, then gradually add it to the base while stirring. Always perform a laboratory compatibility test before full-scale production.

Frequently Asked Questions

The "T" suffix in WT grades stands for "Tempered." It indicates that the material has undergone a tempering heat treatment process to enhance its toughness and reduce brittleness after hardening.T-grades use nano-scale pigment particles for high transparency, finer dispersion, and superior heat and light resistance. Choose a T-grade when you need transparent or clean, vivid shades.

Yes, WT color paste can be used in both pure-water and water/solvent systems.Yes. The WT series is designed for pure-water formulations and systems where water and co-solvents coexist, without shock or flocculation.

What are the heat and light resistance properties of WT pastes?Most grades withstand temperatures up to 240°C and achieve lightfastness grade 8. Exact values vary by pigment — refer to the color chart for each model.

How should WT color paste be incorporated into a formulation?Pre-dilute with deionized water at 1:1 or 1:2, then add slowly while stirring for optimal gloss and compatibility.
