Description

2-Propenoic Acid, 2-Methyl-, Eicosyl Ester, Polymer With Hexadecyl 2-Methyl-2-Propenoate, 2-Methylpropyl 2-Methyl-2-Propenoate And Octadecyl 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 outstanding durability, water repellency, and chemical resistance in demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and personal care industries seeking to enhance product performance and longevity.

Application

• Industrial & Protective Coatings: Used as a key film-forming agent and modifier to improve scratch resistance, gloss, and weatherability in automotive, marine, and architectural coatings.
• Adhesives & Sealants: Imparts flexibility, adhesion, and water resistance to pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding agents.
• Personal Care & Cosmetics: Functions as a film former and fixative in long-wear nail polishes, hair styling products, and sunscreens, providing a durable, non-tacky finish.
• Textile & Leather Finishes: Applied as a coating to confer water and stain repellency, softness, and improved abrasion resistance to fabrics and leather goods.
• Printing Inks: Enhances rub resistance, gloss, and adhesion properties in overprint varnishes and specialty ink formulations.
• Plastic Additives: Acts as a processing aid and impact modifier to improve the surface characteristics and mechanical properties of polymer blends.
