Description

2-Propenoic acid, 2-methyl-, polymer with 2-ethylhexyl 2-propenoate, N-(hydroxymethyl)-2-propenamide, methyl 2-methyl-2-propenoate and 2-methyl-2-[(1-oxo-2-propenyl) amino]-1-propanesulfonic acid CAS NO 123774-68-5 is a specialized multi-component acrylic copolymer engineered for high-performance applications. This advanced polymer is valued for its unique balance of properties derived from its carefully selected monomer composition, including adhesion, film formation, and stability. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical industries seeking to enhance product durability and functionality.

Application

• Industrial and Protective Coatings: Used as a key binder or additive to improve adhesion, chemical resistance, and weatherability in metal, wood, and plastic coatings.
• Pressure-Sensitive Adhesives (PSAs): Provides excellent tack, peel strength, and cohesion for labels, tapes, and graphic films.
• Textile and Leather Finishes: Imparts water resistance, softness, and durability to fabrics and leather goods.
• Paper Coatings: Enhances surface strength, printability, and barrier properties in high-quality paper and packaging.
• Construction Chemicals: Serves as a modifier in cementitious products, sealants, and caulks to improve flexibility and water resistance.
• Specialty Binders: Employed in non-woven binders, glass fiber sizing, and other composite materials for enhanced performance.

Quality Control

Our production of this advanced acrylic copolymer adheres to strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure consistent performance in viscosity, solids content, pH, and monomer residue levels. Certificates of Analysis (COA) detailing all critical parameters 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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
