Description

2-Propenoic Acid, 2-Methyl-, Polymer With Octadecyl 2-Methyl-2-Propenoate is a high-performance copolymer of methyl methacrylate and stearyl methacrylate, designed to deliver exceptional compatibility and film-forming properties. This specialized polymer is engineered to act as a key modifier, enhancing the durability, flexibility, and surface characteristics of finished products. It is an essential raw material for manufacturers in the coatings, adhesives, and plastics industries seeking to improve product performance and processing.

Application

• Coatings & Paints: Used as a rheology modifier, dispersing agent, and film-forming agent to improve leveling, scratch resistance, and gloss in industrial, automotive, and architectural coatings.
• Adhesives & Sealants: Imparts flexibility, adhesion, and cohesive strength to pressure-sensitive adhesives (PSAs), hot-melt adhesives, and construction sealants.
• Plastics & Polymer Modification: Acts as a processing aid and impact modifier in PVC, acrylics, and other thermoplastic compounds to enhance flow properties and reduce melt fracture.
• Printing Inks: Serves as a binder and gloss enhancer in solvent-based and UV-curable printing inks, improving rub resistance and substrate adhesion.
• Personal Care & Cosmetics: Utilized as a film former and viscosity control agent in nail polishes, hair sprays, and sunscreens to provide long-lasting, water-resistant films.
• Textile & Leather Finishing: Applied in fabric coatings and leather finishes to provide a soft hand feel, water repellency, and durability.
