Description

2-Propenoic Acid, 2-Methyl-, 2-Hydroxyethyl Ester, Polymer With Butyl 2-Propenoate, Ethenylbenzene And Methyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer offers a unique balance of properties, including excellent adhesion, chemical resistance, and film-forming characteristics, making it a versatile raw material. It is primarily utilized in the formulation of advanced coatings, adhesives, and sealants where durability and performance are critical.

Application

• Industrial and Protective Coatings: Used as a key binder in solvent-based or high-solid coatings for metal, plastic, and wood substrates, providing corrosion resistance and weatherability.
• Adhesive Formulations: Serves as a primary polymer in pressure-sensitive adhesives (PSAs), structural adhesives, and laminating agents due to its strong adhesion to various surfaces.
• Automotive Refinish and OEM Coatings: A critical component in primers, basecoats, and clearcoats, offering excellent gloss retention and resistance to chemicals and environmental etching.
• Plastic Coatings and Inks: Enhances the printability and surface finish of plastics, used in coatings for consumer electronics and in specialty printing inks.
• Construction Sealants and Caulks: Imparts flexibility, adhesion, and durability to sealants used in building and construction applications.
• Textile and Leather Finishes: Applied as a coating or binder to provide water repellency, abrasion resistance, and improved hand feel to fabrics and leather goods.

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 molecular weight distribution, glass transition temperature (Tg), solids content, viscosity, and monomer residue levels 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, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. Always refer to the specific product label or Safety Data Sheet (SDS) for detailed handling and storage instructions.
