Description

2-Propenoic Acid Polymer With Ethyl 2-Propenoate, Methyl 2-Propenoate And 2-Propene-Nitrile, Ammonium Salt is a water-soluble, anionic copolymer supplied as an ammonium salt. This versatile polymer is engineered to deliver excellent binding, thickening, and film-forming properties in aqueous systems. It is a critical raw material for formulators in industries requiring high-performance, environmentally friendly additives.

Application

• Adhesives & Sealants: Acts as a primary binder and rheology modifier in water-based pressure-sensitive adhesives (PSAs) and construction sealants.
• Coatings & Paints: Serves as a thickener, stabilizer, and pigment dispersant in latex paints and industrial coatings to improve application properties and film integrity.
• Textile Processing: Used as a sizing agent, finishing chemical, and thickener for pigment printing pastes to enhance fabric handle and color fastness.
• Paper & Packaging: Functions as a coating binder and strength additive to improve printability, gloss, and water resistance of paper and paperboard.
• Construction Materials: Employed as a water-retention agent and workability aid in cement-based products like tile adhesives, grouts, and self-leveling compounds.
• Personal Care: Utilized as a film former and stabilizer in hair styling gels, mousses, and skin care formulations.
