Introduction
WQ-2257 is a next-generation polymer emulsion produced through a
core-shell polymerization process. It is a styrene-acrylic
copolymer that forms films through self-crosslinking at room
temperature, specifically engineered for water-based gravure
printing inks. This product exhibits excellent compatibility with
widely used acrylic polymers in the market. Furthermore, it
demonstrates superior pigment wetting properties in gravure ink
applications.
