WQ-2090 Water Based Acrylic Emulsion
Introduction
WQ-2090 is a non-film-forming styrene-acrylic copolymer emulsion
designed specifically for water-based overcoat varnishes and
printing inks. Varnishes utilizing this product exhibit rapid
drying and high gloss, alongside exceptional water resistance and
anti-blocking properties. It demonstrates excellent compatibility
with popular acrylic polymers available in the market. As it does
not independently form a film, it necessitates the use of
compatible film-forming agents or can be blended with smaller
particle size film-forming acrylic emulsions like our WQ-2027,
WQ-2024, WQ-2018, WQ-2015, among others. Moreover, it provides
effective pigment wetting in flexographic and gravure inks.
