Styrene-Acrylic Emulsion Resin
Styrene-Acrylic Emulsion Resin is a core-shell copolymer binder combining styrene hardness with acrylic elasticity, supplied as a milky-white aqueous dispersion with solid content of 45–50% and glass transition temperature (Tg) ranging from -5 to +40°C depending on monomer ratio. It is the workhorse binder for interior and exterior architectural latex paints, including semi-gloss and gloss formulations, where scrub resistance, wet adhesion, and color retention are required. The core-shell morphology delivers a favorable hardness-flexibility balance while minimizing surfactant demand and improving early water resistance.
