Description

2-Propenoic Acid, Polymer With Butyl 2-Propenoate And 2-Propenenitrile, Ammonium Salt is a water-soluble, anionic acrylic 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 the coatings, adhesives, and construction industries seeking to enhance performance while meeting environmental regulations.

Application

• Architectural and Industrial Coatings: Acts as a primary binder and thickener in water-based paints, providing scrub resistance, adhesion, and stability.
• Adhesives and Sealants: Used as a key component in pressure-sensitive adhesives (PSAs) and construction sealants for its cohesive strength and tack.
• Construction Chemicals: Functions as a redispersible powder or liquid additive in cementitious renders, tile adhesives, and self-leveling compounds to improve workability and flexural strength.
• Textile and Nonwovens: Serves as a binder and stiffening agent for fiber bonding and fabric finishing applications.
• Paper Coatings: Enhances the strength, gloss, and printability of paper and paperboard coatings.
• Leather Finishing: Provides a flexible, durable topcoat for leather goods.
