Description

2-Propenoic acid, 2-methyl-, dodecyl ester, polymer with eicosyl 2-methyl-2-propenoate, hexadecyl 2-methyl-2-propenoate, methyl 2-methyl-2-propenoate, octadecyl 2-methyl-2-propenoate and tetradecyl 2-methyl-2-propenoate is a high-performance, long-chain alkyl methacrylate copolymer designed to deliver exceptional film-forming and surface-modifying properties. This specialty polymer is engineered to provide enhanced hydrophobicity, flexibility, and compatibility with a wide range of organic matrices. It is a critical raw material for formulators in the coatings, adhesives, and personal care industries seeking to improve product durability and performance.

Application

• Industrial & Protective Coatings: Used as a key film-forming agent and modifier to improve water resistance, flexibility, and gloss in metal, wood, and plastic coatings.
• Adhesives & Sealants: Imparts tack, enhances cohesive strength, and improves compatibility with various resins and fillers in pressure-sensitive and structural adhesive formulations.
• Personal Care & Cosmetics: Functions as a film former and fixative in hair sprays, mascaras, and sunscreens, providing water resistance and long-lasting wear.
• Printing Inks: Enhances pigment dispersion, printability, and rub resistance in solvent-based and UV-curable ink systems.
• Textile & Leather Finishes: Applied as a finishing agent to provide a soft hand feel, water repellency, and improved abrasion resistance.
• Plastic Additives: Acts as a processing aid and impact modifier to improve the surface characteristics and mechanical properties of polymer blends.
