Description

2-Propenoic Acid Polymer With Butyl 2-Propenoate, Ethenylbenzene And (1-Methylethenyl)Benzene, Sodium Salt is a specialized, water-soluble copolymer designed for high-performance applications requiring excellent film-forming, binding, and stabilizing properties. This versatile polymer is valued for its ability to modify rheology, enhance adhesion, and provide consistent performance in demanding formulations. It is an essential raw material for manufacturers in the coatings, adhesives, construction chemicals, and textile processing industries seeking reliable and effective polymeric additives.

Application

• Coatings & Paints: Acts as a binder and film-forming agent in water-based architectural and industrial coatings, improving scrub resistance and durability.
• Adhesives & Sealants: Used as a key polymeric component in pressure-sensitive adhesives (PSAs) and construction sealants to enhance tack, cohesion, and water resistance.
• Construction Chemicals: Serves as a rheology modifier and redispersible polymer powder in cementitious mortars, tile adhesives, and exterior insulation finishing systems (EIFS).
• Textile Processing: Functions as a finishing agent and binder for non-woven fabrics and textile coatings, providing stiffness, hand feel, and wash-fastness.
• Paper & Packaging: Employed as a coating binder and strength additive to improve printability, surface gloss, and wet-rub resistance of paper and board.
• Personal Care: Utilized as a film former and stabilizer in hair styling products, mascara, and other cosmetic formulations that require water resistance and hold.
