RK-4136B Hyperdispersant

RK-4136B Hyperdispersant

Characteristics and Advantages

This product is a high molecular weight dispersant with excellent dispersing performance of carbon black and organic pigments, with excellent effect: good storage stability, no regrind, significant reduction of pigment milling viscosity, excellent color spreading performance and covering ability. It is the best choice for dispersing FW200, 5000, SB6 and other high pigment carbon black and organic pigments. It also has excellent dispersing performance for other hard-to-dispersed organic pigments such as phthalocyanine blue and matte powder.
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.
