9274 deflocculates the pigment through steric hindrance stabilization. Due to the small particle size of the deflocculated pigment, it can obtain high gloss and improve the color intensity. In addition, the transparency of transparent pigments and the hiding power of opaque pigments are also improved. Due to the decrease of viscosity, the flow performance is improved and the pigment content can be increased. This product has a strong viscosity reduction effect, low foaming, does not need to add defoamer in grinding process and can improve luster. The additive is particularly suitable for the production of stable, resin-free pigment concentrate with a pigment content of 30-60%, which can be used for paint mixing of standard water-based base materials.
