High Gloss Acrylic Emulsion For Water Based Flexographic Varnish And Ink For Polyethylene Bag
Introduction
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, 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 alone, so 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. In addition, in flexo and gravure inks, the product has good pigment wetting.
We recommmed use WQ-2090 and WQ-2015 soft film-forming together for water based flexographic varnish and ink for polyethylene bag, shipping bag. Here is our recommend formula:
