WQ-2011 Water Based Acrylic Emulsion
Introduction
WQ-2011 is a non-film forming, hard styrene and acrylic copolymer emulsion specifically formulated for water based overprint varnishes and printing inks. The varnish formulated with WQ-2011 has fast drying, excellent re-solubility and high gloss, excellent water resistance and anti-sticking properties. Also it has good pigment wetting in flexography and gravure inks.
WQ-2011 has good compatibility with the popular acrylic polymers on the market. Since WQ-2011 cannot form film by itself, it must be used with right film-forming acrylic emulsions, such as our film-forming acrylic emulsions WQ-234, WQ-227 etc.
