Introduction
GKB8190 is a non-film forming rigid styryl-acrylic copolymer emulsion specially designed for waterborne varnish and printing inks. The varnish formulated with this product has a fast-drying speed and high gloss, excellent water resistance and anti-sticky back properties, and it has good compatibility with the popular acrylic polymers in the market. Since this product cannot film by itself, it must be used with a suitable film-forming agent or mixed with a film-forming acrylic emulsion with a small particle size, in addition, in relief and gravure inks, this product has a good pigment wetting ability.
