Styrene Acrylic Emulsion Polymer
Original price was: KSh85,000.00.KSh84,000.00Current price is: KSh84,000.00.
Styrene Acrylic Emulsion Polymer is a versatile water-based copolymer that combines the beneficial properties of styrene and acrylic components to create a high-performance binding agent. This polymer emulsion is particularly valued for its excellent film-forming characteristics, offering an optimal balance between hardness from styrene and flexibility from acrylic. It serves as a key ingredient in various industrial and commercial applications, including architectural and industrial coatings, where it provides durability, water resistance, and enhanced gloss retention. Additionally, it is widely used in adhesives and sealants for its strong bonding capabilities, in textile and paper coatings for improved wash resistance and printability, and in construction materials to enhance waterproofing and crack resistance in concrete mixtures
