Description

2-Propenoic Acid, Butyl Ester, Polymer With Ethenylbenzene is a high-performance copolymer widely utilized in industrial formulations for its excellent film-forming and binding properties. This material is engineered to provide enhanced durability, adhesion, and chemical resistance in demanding applications. It is a critical component for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced material science applications.

Application

• Industrial Coatings: Used as a primary binder in solvent-based and high-solids coatings for metal, plastic, and wood substrates, offering excellent gloss, hardness, and weatherability.
• Adhesives and Sealants: Serves as a key polymer in pressure-sensitive adhesives (PSAs), construction sealants, and assembly adhesives, providing strong tack and cohesive strength.
• Textile and Non-Woven Binders: Applied as a durable binder for fiber bonding in non-woven fabrics, textile finishing, and pigment printing, enhancing wash and abrasion resistance.
• Paper and Packaging Coatings: Functions as a coating resin to improve surface gloss, printability, and water resistance of paperboard and packaging materials.
• Leather Finishing: Employed in topcoat formulations for leather goods to provide a flexible, protective, and aesthetically pleasing finish.
• Caulks and Putties: Imparts flexibility, adhesion, and longevity to automotive and industrial caulking compounds and fillers.

Quality Control

Our 2-Propenoic Acid, Butyl Ester, Polymer With Ethenylbenzene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including measurement of solid content, viscosity, glass transition temperature (Tg), and residual monomer levels. Certificates of Analysis (COA) documenting all key parameters are available upon request 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 room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent moisture absorption and skin formation.
