Styrene-Acrylic Copolymer Emulsion For Water-Based Overprint Varnishes And Inks
Introduction
WQ-2090 non-film forming hard styrene-acrylic copolymer emulsion is a fast drying styrene-acrylic copolymer emulsion. WQ-2090 has high gloss and good heat resistance, and it also provides good heat seal and film release properties. WQ-2090 styrene acrylic copolymer is suitable for use in water-based overprint varnishes and flexographic and gravure inks.
The varnish formulated withWQ-2090 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.
