Description

2-Propenoic Acid, 2-Methyl-, Hexadecyl Ester, Polymer With Isodecyl 2-Methyl-2-Propenoate And Octadecyl 2-Methyl-2-Propenoate is a high-performance, long-chain alkyl methacrylate copolymer designed to impart exceptional durability and specific surface properties to industrial formulations. This polymer is valued for its ability to modify rheology, enhance water repellency, and improve the flexibility and adhesion of coatings and films. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and plastics industries seeking to develop advanced, high-value products.

Application

• Industrial Coatings Modifier: Used to enhance the flexibility, water resistance, and durability of solvent-borne and high-solid industrial and protective coatings.
• Adhesive & Sealant Formulations: Acts as a key polymer component to improve tack, adhesion to low-energy surfaces, and long-term weatherability.
• Plastic Additive: Employed as a processing aid and impact modifier to improve the surface finish and mechanical properties of engineered plastics.
• Printing Ink Binder: Provides robust binding properties and rub resistance in specialty printing inks for packaging and publications.
• Textile & Leather Finishing: Imparts water and stain repellency, as well as a soft hand feel, to treated fabrics and leather goods.
• Personal Care & Cosmetic Ingredient: Functions as a film-forming agent and viscosity modifier in hair sprays, sunscreens, and nail polishes.
