Hyperdispersant

RK-4028 Hyperdispersant

Characteristics and advantages

This product is a polymer dispersant, excellent dispersing performance of inorganic and organic pigments, with excellent effect: good wettability, good storage stability, no return to roughness, significantly reduce the viscosity of pigment grinding, excellent color spreading performance and covering ability. It is the best choice for dispersing FW200, 5000, SB6 and other high pigment carbon blacks. It has excellent dispersing performance for other hard-to-dispersed organic and inorganic pigments such as phthalocyanine blue.
Good pigment wettability, shorten the dispersion process, can reach the spatial resistance effect effectively prevent pigment flocculation and settlement, due to the dispersed pigment tiny particle size, the system can obtain excellent color and gloss.
