Description

2-Propenoic Acid, 2-Methyl-, Dodecyl Ester, Polymer With Octadecyl 2-Methyl-2-Propenoate CAS NO 56631-89-1 is a high-performance, long-chain alkyl methacrylate copolymer designed for advanced material science applications. This polymer is valued for its excellent film-forming properties, water resistance, and compatibility with a wide range of organic substrates. It is primarily utilized by formulators in the coatings, adhesives, and specialty plastics industries seeking to enhance durability and surface characteristics.

Application

• Industrial Coatings: Used as a key film-forming agent in solvent-based and high-solids coatings for metal, plastic, and wood, providing excellent gloss, hardness, and chemical resistance.
• Adhesives and Sealants: Serves as a tackifier and modifier in pressure-sensitive adhesives (PSAs) and construction sealants, improving adhesion, cohesion, and flexibility.
• Printing Inks: Incorporated into overprint varnishes and specialty inks to enhance rub resistance, gloss, and drying properties.
• Plastic Additives: Acts as a processing aid and impact modifier for engineering plastics, improving flow properties and surface finish.
• Leather and Textile Finishing: Applied in topcoat formulations for leather and fabric to impart water repellency, a soft hand feel, and abrasion resistance.
• Personal Care Products: Utilized in hair styling resins and nail polish formulations to provide durable film formation and water resistance.
