Styrene-Acrylic Emulsion
Styrene-acrylic emulsions are copolymer binders combining styrene for hardness and acrylic monomers for flexibility and weather resistance, widely used in exterior masonry paints, renders, and paper coatings. They offer a cost-performance balance between pure acrylics and vinyl acrylics, delivering good water resistance, tint retention, and adhesion. These binders are available in a range of glass transition temperatures to suit flat, semi-gloss, and gloss coating applications.
