With the continuous expansion of coating application scenarios, the demand for coating quality stability is also increasing. Color paint is widely used in various occasions, so its stability is particularly important. In the production process using colorants as a color matching method, pre made specialized colorants or universal colorants are required to have good display properties and maintain color consistency during storage, that is, they must have good "color display properties". This is crucial in the paint manufacturing process

The main reason for poor color display is that the coagulation of pigments weakens their coloring power. When using different pigment dispersants to disperse pigments, a re equilibrium phenomenon of adsorption/desorption occurs after mixing, resulting in the loss of pigment stability and coagulation. Therefore, attention must be paid to the role of dispersants in each color paste when matching colors

To maintain the stability of the color paste performance, a series of complex and important technical measures need to be taken. Here are some of our suggestions for reference only:

1. Choose pigments with very stable quality

2. Select appropriate wetting agents and dispersants

3. The selection of wetting agents and dispersants should be appropriate

4. Select appropriate grinding resins, stabilizing resins, or water-based thickeners

5. Use the same type of dispersant as much as possible in the formula to avoid violent chemical reactions that can cause instability

6. Choosing high molecular weight hyperdispersants can help improve stability

7. Select dispersing equipment with high shear force

8. Conduct thorough stability experiments on the color paste

These measures help improve the stability of coating quality and provide more reliable guarantees for the application of color paints in various occasions
