Description

2-Propenoic Acid, Polymer With Ethyl 2-Propenoate, Ammonium Salt is a water-soluble, anionic acrylic copolymer supplied as an ammonium salt. This polymer is valued for its excellent film-forming, binding, and dispersing properties, making it a versatile additive in numerous industrial formulations. It is primarily used by manufacturers in the coatings, adhesives, textiles, and personal care industries seeking to enhance product performance and stability.

Application

• Coatings & Paints: Acts as a binder and film-former in water-based architectural and industrial coatings, improving adhesion and durability.
• Adhesives & Sealants: Used as a key component in pressure-sensitive adhesives (PSAs) and construction sealants for its cohesive strength and tack.
• Textile Processing: Serves as a finishing agent, thickener, and binder for pigments and dyes on fabrics.
• Personal Care & Cosmetics: Functions as a film-forming agent, thickener, and stabilizer in hair styling products, creams, and lotions.
• Paper & Packaging: Employed as a coating binder and strength additive to improve printability and water resistance.
• Construction Materials: Used as a redispersible powder or additive in cementitious products and tile adhesives to modify rheology and enhance bond strength.
