Water Based Acrylic Emulsion Polymer For Flexographic Printing Ink
WQ-290 Water Based Acrylic Emulsion
Introduction
WQ-290 is a non-film forming hard styrene-acrylic copolymer emulsion specially formulated for waterborne overcoat varnishes and printing inks. The varnish formulated with this product has fast drying speed and high gloss, excellent water resistance and anti-stick back performance, and it has good compatibility with popular acrylic polymers on the market. Since this product cannot form a film by itself, it must be used with a suitable film-forming additive or mixed with a film-forming acrylic emulsion with a smaller particle size. In addition, this product has good pigment wetting in flexo and gravure inks ability.
