Wetting and Dispersing Additive

RK-4016A Wetting and Dispersing Additive

Characteristics and Advantages：

This product is a polymer dispersant with polyurethane structure, excellent carbon black dispersing performance, excellent effect: good storage stability, no return to coarseness, significantly reduce the viscosity of pigment grinding, excellent color spreading performance and covering ability. Excellent grinding and dispersing effect on inorganic and organic pigments.

Good pigment wettability, shorten the dispersion process, can reach the spatial resistance effect to effectively prevent the pigment flocculation and settlement, due to the dispersion of the pigment tiny particle size, the system can obtain excellent color and gloss.
