Description

2-Propenoic acid, 2-methyl-, butyl ester, polymer with dodecyl 2-methyl-2-propenoate, pentadecyl 2-methyl-2-propenoate, tetradecyl 2-methyl-2-propenoate and tridecyl 2-methyl-2-propenoate CAS NO 65379-38-6 is a high-performance acrylic copolymer designed for advanced material formulations. This specialized polymer offers a unique balance of properties derived from its tailored alkyl methacrylate composition, making it a versatile additive and film-forming agent. It is primarily utilized in industries requiring durable coatings, adhesives, and specialty polymers where consistent performance and material compatibility are critical.

Application

• Industrial and Protective Coatings: Used as a key resin or modifier in solvent-borne and high-solids coatings to enhance durability, gloss, and chemical resistance.
• Pressure-Sensitive Adhesives (PSAs): Functions as a tackifier and film-former, providing balanced adhesion and cohesion properties for label and tape applications.
• Printing Inks: Imparts improved rub resistance, gloss, and binding properties in specialty ink formulations for packaging and publications.
• Plastic Additives: Acts as a processing aid, impact modifier, or compatibilizer in polymer blends and composites.
• Textile and Leather Finishes: Employed in coatings and finishes to provide water repellency, softness, and abrasion resistance.
• Sealants and Caulks: Contributes to elasticity, adhesion, and weather resistance in construction and automotive sealant formulations.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for industrial applications. Quality is verified through parameters including viscosity, solid content, acid value, and glass transition temperature (Tg). A Certificate of Analysis (COA) detailing specific lot results is provided with every shipment to guarantee it meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent moisture absorption or solvent evaporation.
