The super dispersant
RD-9779
Features and Advantages:
RD - 9779 belongs to the copolymer containing acidic groups, water and oil and general, not only has good wettability, also has the very good anti-settling ability, for all kinds of inorganic fillers with excellent viscosity and dispersion ability, at the same time of lapping paste has strong ability to prevent flocculation return thick, increase the storage stability of the printing ink, suitable for all kinds of system of polarity, Especially in the medium and high polarity system has excellent effect, can significantly improve the wetting and dispersion ability of the base material to the color and filler, reduce the viscosity of the system, improve the fluidity, shorten the grinding and dispersion time. Widely used in SMC and BMC systems.
