Product Description

Styrene Acrylic Emulsion For Water Based Varnish For PE Double Coated Paper


WQ-2090 Water Based Acrylic Emulsion



WQ-2090 is a hard non-film-forming styrene-acrylic copolymer emulsion specially formulated for water-based overcoat varnishes and printing inks. The varnish formulated with this product has fast drying speed and high gloss, good water resistance and anti-stick back performance, and it has good compatibility with popular acrylic polymers on the market. Because this product cannot form a film alone, it must be used with a suitable film-forming aids or mixed with a film-forming acrylic emulsion with a smaller particle size, such as used with our film-forming varnish emulsion WQ-2027, WQ-2024, WQ-2018, WQ-2015, etc. Besides, in flexo and gravure inks, the product has excellent pigment wetting.
