Eagle Styrene Acrylic 72/50
Eagle Styrene Acrylic 72/50 is a co-polymer emulsion consisting of styrene and acrylic monomers, offered at 50% active solids concentration in water. It appears as a milky-white, low-viscosity liquid with a mild odor. This polymer emulsion combines excellent film-forming properties, adhesion, and mechanical strength, making it widely used in coatings, adhesives, sealants, and functional binders across multiple industries.
