Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethenylbenzene And 1,2-Propanediol Mono-2-Propenoate CAS NO 66330-14-1 is a high-performance, multi-component acrylic copolymer designed to deliver exceptional film-forming, adhesive, and protective properties. This specialized polymer is engineered to provide a critical balance of durability, flexibility, and chemical resistance for demanding industrial applications. It is an essential raw material for formulators in the coatings, adhesives, and construction chemical sectors seeking to enhance product performance and reliability.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, industrial topcoats, and corrosion-resistant paints, offering excellent adhesion and weatherability.
• Architectural Coatings: Serves as a film-forming agent in exterior and interior paints, providing scrub resistance, low dirt pickup, and durability.
• Adhesives and Sealants: Imparts strong bonding strength and flexibility in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives.
• Textile and Leather Finishes: Applied as a coating or binder to provide water resistance, abrasion resistance, and a soft hand feel to treated fabrics and leathers.
• Paper and Packaging Coatings: Enhances surface gloss, printability, and water resistance of paperboard and packaging materials.
• Construction Chemicals: Incorporated into cementitious modifiers and tile adhesives to improve flexibility, water retention, and bond strength.

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 including monomer content, molecular weight distribution, viscosity, and glass transition temperature (Tg) are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is 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 15-25°C (59-77°F). Avoid exposure to extreme heat or freezing conditions to maintain product stability and prevent phase separation or changes in viscosity. Keep away from strong oxidizing agents.
