Introduction
WQ-2011L is a hard, non-film-forming styrene-acrylic copolymer emulsion, engineered specifically for formulating high-performance water-based overprint varnishes (WBOV) and printing inks. Varnishes based on WQ-2011L exhibit rapid curing, a superior glossy finish, outstanding water resistance, and exceptional block resistance. Furthermore, it delivers excellent pigment wetting and dispersion characteristics for water-based flexographic and gravure ink applications.
