Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate And Ethenylbenzene, Ammonium Salt is a water-soluble, anionic acrylic copolymer supplied as an ammonium salt. This specialized polymer is engineered to deliver robust performance as a film-forming agent, binder, and rheology modifier in aqueous systems. It is a critical raw material for formulators in the coatings, adhesives, and construction chemicals industries seeking to enhance product durability, adhesion, and application properties while maintaining environmental compliance.

Application

• Architectural and Industrial Coatings: Acts as a primary binder and film-former in interior/exterior paints, providing excellent scrub resistance, adhesion to various substrates, and improved pigment binding.
• Adhesives and Sealants: Serves as a key component in water-based pressure-sensitive adhesives (PSAs) and construction sealants, contributing to tack, peel strength, and cohesion.
• Construction Chemicals: Used as a rheology modifier and binder in cementitious formulations, tile adhesives, grouts, and self-leveling compounds to improve workability, water retention, and flexural strength.
• Textile and Nonwovens: Functions as a binder for fiber bonding and as a coating agent to impart stiffness, hand feel, and durability to fabrics.
• Paper and Paperboard Coatings: Enhances surface strength, printability, and gloss in coating formulations for paper and packaging materials.
• Leather Finishing: Utilized in topcoat formulations to provide a flexible, durable, and protective film that enhances the aesthetic and functional properties of finished leather.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as solids content, viscosity, pH, particle size, and minimum film-forming temperature (MFFT) are rigorously monitored. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 5°C and 30°C (41°F and 86°F). Protect from freezing and prolonged exposure to elevated temperatures to maintain product stability and prevent coagulation or viscosity changes.
