Description

2-Propenoic acid, 2-methyl-, methyl ester, polymer with ethyl 2-propenoate, N-(hydroxymethyl)-2-propenamide and 2-propenoic acid Acrylic acid, ethyl acrylate, methyl methacrylate, N-methylolacrylamide polymer CAS NO 30643-08-4 is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer is valued for its excellent film-forming properties, adhesion, and chemical resistance, making it a critical raw material for advanced coating systems. It is primarily sought by manufacturers in the paints and coatings, adhesives, textiles, and paper industries seeking to enhance product durability and performance.

Application

• Industrial and Architectural Paints & Coatings: Used as a key binder to provide durability, gloss retention, and weather resistance in water-based and solvent-based formulations.
• Adhesives and Sealants: Imparts strong adhesion to diverse substrates and enhances cohesive strength in pressure-sensitive and structural adhesives.
• Textile Finishing and Coatings: Applied as a finishing agent to improve fabric hand feel, wrinkle resistance, and water repellency.
• Paper Coatings and Sizing: Enhances surface strength, printability, and oil/water resistance of paper and paperboard.
• Leather Finishing: Used in topcoat formulations to provide a protective, flexible, and glossy finish.
• Crosslinking Component: The N-methylolacrylamide units can provide sites for thermal or catalytic crosslinking, improving film hardness and solvent resistance.

Quality Control

Our acrylic copolymer is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including solid content, viscosity, pH, and monomer residue levels. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Avoid freezing and prolonged exposure to extreme heat. Keep away from strong oxidizing agents.
