What is resin free pigment color paste?
The using of pigment color paste can make paint production easier, and reduce the paint grinding process. No pigment powder is added, it will be good for paint quality. When we put pigment paste in the formula of paint producing, the paint can show better color display and color saturation than pigment powders, and also reduce the cost.
During the manufacturing of water based pigment paste, pigment powder is the most important color material, water is the main raw material. And how can we disperse pigment powder uniformly and stably in water or other solvents? We need to add small quantity dispersant and emulsifier, but no resin material.
Most of pigment paste factories would put certain amount of resin liquid in pigment paste formulation in order to improve the stability of pigment particles in water or other solvents. Resin will coat well pigment particles to ensure the stability of pigment. But resin free pigment paste is that no resin should be added in pigment paste production, we just choose one or two dispersant to stabilize the pigment color paste system. Superior dispersants will be widely adapted to a lot of paint formulations. The difference between no resin pigment paste and resin pigment paste is that no resin pigment paste has a wider range of applications.
