1. Product Introduction & Main Application
Arnico’s Acrylic Styrene is a milky-white, water-based copolymer emulsion produced by the polymerization of acrylate monomers with styrene. This versatile resin, due to its ability to form a clear, hard, and water-resistant film, is recognized as the primary binder in the production of semi-gloss architectural paints, decorative coatings, and paper adhesives, serving as the bridge between quality and economic efficiency.
