Description

2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylbenzene, ethyl 2-propenoate, 2-hydroxyethyl 2-methyl-2-propenoate and methyl 2-methyl-2-propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer's complex composition provides a unique balance of properties, including excellent film formation, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and specialty polymer industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key binder in high-performance paints and varnishes for metal, wood, and plastic substrates, offering weatherability and corrosion resistance.
• Adhesives and Sealants: Serves as a primary polymer in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives, providing strong bonding and flexibility.
• Textile and Leather Finishes: Applied as a coating or finishing agent to improve the handle, durability, and water resistance of fabrics and leather goods.
• Paper and Packaging Coatings: Enhances the surface strength, printability, and barrier properties of paper, cardboard, and other packaging materials.
• Specialty Inks: Formulated into flexographic and gravure inks for packaging, providing excellent adhesion and rub resistance on non-porous surfaces.
• Construction Materials: Incorporated into cement modifiers, tile adhesives, and waterproofing membranes to improve cohesion, flexibility, and water resistance.

Quality Control

Our production of this advanced acrylic copolymer adheres to stringent quality management systems, including ISO 9001 standards. Every batch undergoes comprehensive analysis to ensure consistent performance parameters such as molecular weight distribution, glass transition temperature (Tg), viscosity, solids content, and monomer residue levels. Certificates of Analysis (COA) detailing these specifications are provided and 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). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity.
