Description

2-Propenoic acid, 2-methyl-, butyl ester, polymer with butyl 2-propenoate, ethenylbenzene, methyl 2-methyl-2-propenoate, 1,2-propanediol mono-2-propenoate and 2-propenoic acid CAS NO 64614-15-9 is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties, including excellent adhesion, chemical resistance, and film-forming characteristics. It is a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, topcoats, and corrosion-resistant paints for automotive, machinery, and structural steel.
• Adhesives and Sealants: Serves as a primary resin component in high-strength structural adhesives, pressure-sensitive adhesives (PSAs), and flexible sealants.
• Printing Inks: Formulated into overprint varnishes and specialty inks to provide gloss, rub resistance, and substrate adhesion.
• Textile and Leather Finishes: Applied as a coating or binder to impart water repellency, durability, and a desired hand-feel to fabrics and leather goods.
• Plastic and Composite Modification: Utilized as an impact modifier or compatibilizer to improve the toughness and processing of polymer blends.
• Construction Chemicals: Incorporated into cementitious modifiers, tile adhesives, and waterproofing membranes to enhance flexibility 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 such as solids content, viscosity, acid value, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

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. To prevent skinning or viscosity changes, ensure containers are properly sealed after use. For long-term storage, maintain under an inert atmosphere if specified.
