Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethenylbenzene, Ethyl 2-Propenoate, 2-Propenenitrile And 2-Propenoic Acid CAS NO 125826-34-8 is a specialized multi-component acrylic copolymer designed to deliver a unique balance of properties. This engineered polymer is critical for formulators seeking to enhance the durability, adhesion, and chemical resistance of their final products. It is primarily utilized in the production of high-performance industrial coatings, advanced adhesives, and tailored sealants.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, automotive topcoats, and corrosion-resistant finishes for machinery and structural steel.
• High-Performance Adhesives: Serves as a primary component in pressure-sensitive adhesives (PSAs) for tapes, labels, and laminating films, offering excellent tack and peel strength.
• Construction Sealants and Caulks: Imparts flexibility, weather resistance, and strong substrate adhesion in sealants for joints, windows, and building facades.
• Textile and Leather Finishes: Applied as a coating or binder to provide water repellency, abrasion resistance, and improved hand feel to fabrics and synthetic leather.
• Paper and Packaging Coatings: Enhances the gloss, printability, and moisture barrier properties of paperboard and packaging materials.
• Plastic Modifiers and Impact Improvers: Used as an additive to modify the impact resistance and processing characteristics of engineering plastics.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like molecular weight distribution, glass transition temperature (Tg), and monomer residue levels. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key specifications. We support compliance with global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flames. For long-term storage, ensure containers are sealed to prevent moisture absorption or skin formation.
