Dispersant is a surfactant with two opposite properties, lipophilicity and hydrophilicity, in the molecule. It can evenly disperse the solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, and at the same time prevent the sedimentation and coagulation of particles, forming the amphiphilic reagent required for stable suspension. Aqueous dispersion refers to a specially modified organic phosphate liquid, anionic, with low solubility in water, which can be dispersed in various solvent-based coatings and has excellent anti-settling and dispersing effects in paints and inks.
Aqueous dispersants can effectively adsorb tiny particles originally attached to the surface of the product, and drive away debris by generating static electricity on their own, and can well prevent the driven particles from settling and affecting the subsequent operation of the product. Aqueous dispersants are a colorless or light yellow liquid under normal conditions, usually with a certain viscosity. When adding, they should be used according to the characteristics of the particles attached to the surface of the product and in accordance with the relevant instructions.
The performance characteristics of water-based dispersants are as follows:

  1. It has a good anti-settling effect on silica powder, transparent powder, talcum powder, heavy calcium, etc.;
  2. In PE paint, in addition to helping to prevent settling, it also has an anti-greening effect. Unlike general anti-greening agents that affect drying time, this product has no effect on drying;
  3. It can also have a good anti-settling effect on glass powder, aluminum silver paste, and pearlescent powder with a small amount of anti-settling agent;
  4. As a “thickening agent”, it can effectively prevent the viscosity from increasing due to the thickening of the lead powder;
  5. It has a certain improvement on the floating color and blooming caused by mixed pigments.
