Product Description

Powder dispersant 781

Description
781 is a dispersant for powder coatings, which is a deflocculated low molecular weight polymer. There are many spaces in the molecule close to the pro-pigment and some resin-like segment structures. Adding to the powder formulation and extruding together can improve the wettability of the pigment and the resin, improve the gloss and adhesion, and improve the leveling performance of the surface. Or reduce the amount of pigment to prevent the appearance of floating. It can also improve the hiding power or the thin coating without leaking the bottom. Compared with simply increasing the amount of resin to improve the gloss of the coating film, it has a great cost advantage.
