Description

Ethyl Acrylate, Methyl Methacrylate, Sodium Methacrylate Polymer is a synthetic copolymer designed for high-performance applications. This versatile polymer combines the properties of its constituent monomers to offer excellent film formation, adhesion, and water solubility. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical industries seeking to enhance product durability and functionality.

Application

• Waterborne Coatings & Paints: Acts as a key film-forming agent and binder, providing excellent gloss, weatherability, and adhesion to various substrates.
• Pressure-Sensitive Adhesives (PSAs): Used to formulate adhesives with a balanced tack, peel strength, and shear resistance for labels and tapes.
• Textile & Leather Finishing: Serves as a durable coating and finishing agent to improve scuff resistance, hand feel, and water repellency.
• Paper & Packaging Coatings: Enhances surface strength, printability, and grease resistance of paper and cardboard products.
• Construction Chemicals: Incorporated into cement modifiers and tile adhesives to improve flexibility, water retention, and bond strength.
• Personal Care & Cosmetics: Functions as a film former and stabilizer in hair sprays, mascara, and nail polish for long-lasting effects.
