This additive can quickly and effectively reduce the surface tension of the system, wet the substrate, spread on the surface of the substrate. It can improve adhesion, enhance the surface gloss and improve the color resolution, meanwhile, it can improve leveling to achieve uniform finish and improve the efficiency of color paste grinding, ink printing and paint coating. It is suitable for water-based formulation system, with very good wetting permeability. It can be recommended for the production of stable universal pigment concentrate. It has good compatibility with other additives. It also has good biodegradability and recoatability, low foam, and good compatibility with different polymers.
