Description

2-Propenoic Acid, 2-Methyl-, Polymer With 2-Ethylhexyl 2-Propenoate And Methyl 2-Methyl-2-Propenoate, Ammonium Salt is a water-soluble acrylic copolymer dispersion, specifically an ammonium salt of a terpolymer of methyl methacrylate, 2-ethylhexyl acrylate, and methacrylic acid. This specialized polymer offers excellent film-forming properties, adhesion, and stability, making it a versatile component in advanced industrial formulations. It is primarily utilized in sectors requiring high-performance binders, thickeners, and protective coatings, such as paints, adhesives, textiles, and personal care products.

Application

• Water-Based Paints & Coatings: Acts as a primary binder and film-forming agent, providing excellent gloss, durability, and water resistance.
• Adhesives & Sealants: Used as a key component in pressure-sensitive adhesives (PSAs) and construction sealants for strong, flexible bonds.
• Textile Finishing: Serves as a fabric coating and finishing agent to improve hand feel, wrinkle resistance, and durability.
• Personal Care & Cosmetics: Functions as a film former and thickener in hair styling products, sunscreens, and skin care formulations.
• Paper & Board Coatings: Enhances surface strength, printability, and gloss in paper coating applications.
• Leather Finishing: Used in topcoat formulations to provide a protective, flexible, and glossy finish.
