Dispersants can be divided into low molecular dispersants and high molecular dispersants. The role of dispersants is to use wetting dispersants to reduce the time and energy needed to complete the dispersion process, stabilize the dispersed pigment dispersions, modify the surface properties of pigment particles, and adjust the movement of pigment particles. The commonly used dispersant is pigment dispersant, which reduces the interfacial tension between pigments or fillers and carriers. It is suitable for all coating systems (regardless of solvent-free coatings) and does not affect the application period of two-component systems. Efka dispersant is used for high - quality solvent - based colorants of inorganic and organic pigments against flocculation. Used for dispersing inorganic and organic pigments in high quality solvent - based colorings. Anti float color, flower, phase separation, delay PS material floating time.
