Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 1,3-Butadiene, Ethenylbenzene And Ethyl 2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer offers a unique balance of properties derived from its constituent monomers, including flexibility, adhesion, and chemical resistance. 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 coatings for metal, plastic, and wood substrates, providing excellent weatherability, gloss, and corrosion resistance.
• Adhesives and Sealants: Serves as a primary resin in the formulation of high-strength structural adhesives, pressure-sensitive adhesives (PSAs), and flexible sealants.
• Automotive Finishes: A critical component in primer, basecoat, and clearcoat systems for automotive OEM and refinish applications, enhancing appearance and chip resistance.
• Plastic and Leather Coatings: Provides a durable, flexible, and decorative finish for synthetic leather, vinyl, and various plastic components.
• Industrial Maintenance Paints: Formulated into heavy-duty maintenance paints for infrastructure, pipelines, and industrial equipment exposed to harsh environments.
• Printing Inks: Used in specialty printing inks to improve adhesion, rub resistance, and gloss on non-porous surfaces.

Quality Control

Our acrylic copolymer products are manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against rigorous internal specifications for critical parameters such as solids content, viscosity, molecular weight distribution, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these results 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, sparks, and open flame. For long-term storage, maintain under an inert atmosphere if the product is supplied in a solvent that is easily oxidized.
