Description

Acrylates Copolymer CAS NO 25133-97-5 is a versatile synthetic polymer formed from the polymerization of acrylate and methacrylate monomers. This material is valued for its excellent film-forming, binding, and thickening properties, making it a critical component in numerous industrial and consumer formulations. It is essential for manufacturers in the adhesives, coatings, personal care, and textile industries seeking reliable performance enhancers.

Application

• Adhesives & Sealants: Acts as a primary film-forming agent and tackifier in pressure-sensitive adhesives (PSAs) and construction sealants.
• Coatings & Paints: Used as a binder in architectural paints, industrial coatings, and primers to improve durability, gloss, and water resistance.
• Personal Care & Cosmetics: Serves as a film former, thickener, and stabilizer in hair sprays, sunscreens, lotions, and nail polish.
• Textile & Leather Finishing: Provides stiffness, hand feel improvement, and durable press properties to fabrics and leather goods.
• Printing Inks: Enhances the adhesion, rub resistance, and gloss of inks for flexible packaging and publications.
• Construction Materials: Incorporated into cement modifiers and tile adhesives to improve flexibility, water retention, and bond strength.
