Description

2-Propenoic Acid, 2-Methyl, Butyl Ester, Polymer With Butyl 2-Propenoate, 2-Hydroxypropyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed to deliver exceptional film-forming properties and durability. This specialized polymer is engineered to provide a critical balance of flexibility, adhesion, and chemical resistance 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, topcoats, and anti-corrosion paints, offering excellent weatherability and substrate adhesion.
• Automotive Refinish and OEM Coatings: Provides the necessary hardness, gloss retention, and chemical resistance for automotive clearcoats and color layers.
• Adhesives and Sealants: Serves as a key component in pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding agents, contributing to tack, cohesion, and flexibility.
• Plastic and Wood Coatings: Enhances the finish, scratch resistance, and aesthetic appeal of coatings applied to plastic substrates and furniture.
• Inks and Overprint Varnishes: Utilized in formulations for printing inks and protective varnishes to improve rub resistance, gloss, and drying characteristics.
• Textile and Leather Finishes: Imparts durable, flexible, and water-resistant finishes to fabrics and leather goods.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system 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) detailing all relevant specifications are provided with 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 15-25°C (59-77°F). Avoid freezing and prolonged exposure to heat sources above 40°C (104°F) to prevent premature polymerization or changes in viscosity.
