Dispersants are additives that help wet pigments during the dispersion process, reduce the viscosity of the slurry, make dispersion easier, and stabilize the dispersed particles in the liquid. Therefore, selecting suitable dispersants can greatly improve the color development, system stability, compatibility, and other properties of coatings.

Poor dispersion of the color paste results in significant migration differences between the pigment flocs in the paste and the white pigments and filler particles in the base material, leading to uneven distribution of pigment flocs and resulting in floating and blooming colors. Solution: After adding a suitable dispersant (commonly used in multiple models of Houhuan), the dispersant tightly adsorbs with the pigment particles, narrowing the particle size distribution range and continuously reducing the flocculation degree of the colored pigment particles, thereby improving their color development.

 

Wetting and dispersion are important processes in the preparation of coatings, and wetting and dispersing agents are one of the most important raw materials for coatings. Reasonable use of wetting and dispersing agents can improve the quality of the entire coating product, endow the coating with better performance, and balance the application performance, stability, and water resistance of the coating film.
