Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With 2-Ethylhexyl 2-Propenoate And Ethyl 2-Propenoate is a high-performance acrylic copolymer designed to deliver exceptional film-forming properties, durability, and chemical resistance. This terpolymer is engineered to provide a critical balance of flexibility, adhesion, and weatherability for demanding industrial applications. It is an essential raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a primary binder in metal primers, machinery enamels, and corrosion-resistant topcoats.
• Architectural Coatings: Serves as a key component in exterior paints and stains, providing excellent UV resistance and durability.
• Adhesives and Sealants: Imparts strong adhesion and flexibility in pressure-sensitive adhesives (PSAs), construction sealants, and laminating agents.
• Automotive Refinish: Formulated into clear coats and base coats for automotive refinishing applications requiring high gloss and chemical resistance.
• Plastic Coatings: Enhances adhesion and surface protection for coatings applied to various plastic substrates.
• Inks and Overprint Varnishes: Used in formulations for industrial inks and protective varnishes to improve rub resistance and gloss.

Quality Control

Our acrylic terpolymer is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including monomer content, molecular weight distribution, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting purity, physical properties, and performance characteristics are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flame. For long-term storage under warm conditions, consult the technical data sheet for specific recommendations.
