Features and Benefits
The additive can deflocculate the pigment by stabilizing the steric hindrance. Because the particle size of the deflocculating pigment is small, it can obtain high gloss and improve color intensity. In addition, the transparency of transparent pigments and the hiding power of opaque pigments are also improved. Due to the reduction of viscosity, the flowability is improved and the content of pigment can be increased.
Recommended use
