9553 has excellent ability to prevent back coarsening. It can greatly extend the storage stability of the grinding paste, significantly improve the wetting and dispersing ability of the base material to the pigment and filler, reduce the viscosity of the system, improve the fluidity, and shorten the grinding and dispersing time. This product has good compatibility, especially suitable for grinding high-pigment carbon black and organic pigments as well as can greatly reduce the operating viscosity of the grinding system, increase the pigment load. It is suitable for medium and high polarity system, and has good compatibility and matching with commonly used coating resin. It has good versatility in coating system and can be used for solvent-based coatings such as two-component polyurethane, alkyd, acrylic ester, polyester, amino baking paint, etc.
