Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 1,3-Butadiene, Diethenylbenzene And Ethenylbenzene is a specialized copolymer designed to deliver enhanced performance characteristics. This engineered polymer is valued for its unique balance of properties derived from its acrylic, butadiene, and styrenic components. It serves as a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to improve product durability and flexibility. The compound, identified by CAS No. 9035-90-9, is supplied to meet the stringent demands of industrial manufacturing.

Application

• Industrial and Protective Coatings: Used as a film-forming agent or modifier to enhance flexibility, impact resistance, and adhesion on metal, concrete, and plastic substrates.
• Pressure-Sensitive Adhesives (PSAs): Functions as a key polymer backbone to provide tack, peel strength, and cohesive strength for labels, tapes, and graphic films.
• Sealants and Caulks: Imparts elasticity, weather resistance, and long-term durability to construction and automotive sealant formulations.
• Textile and Leather Finishes: Employed as a binder or coating to improve the scuff resistance, hand feel, and waterproofing of treated fabrics and leathers.
• Paper Coatings: Enhances the gloss, printability, and barrier properties of specialty paper and paperboard products.
• Plastic Modifiers: Acts as an impact modifier or compatibilizer in polymer blends to improve the toughness of rigid plastics.

Quality Control

Our production of this copolymer adheres to rigorous quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer residue, molecular weight distribution, and glass transition temperature (Tg) are strictly monitored. Certificates of Analysis (COA) documenting purity, viscosity, solid content, and other critical specifications are available for every shipment. We support compliance with relevant global regulatory frameworks.

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, consider under an inert atmosphere to prevent oxidation. Keep the container sealed when not in use to minimize moisture absorption and maintain product integrity.
