Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 2-Ethylhexyl 2-Propenoate And 2-Propenoic Acid, Ammonium Salt is a high-performance, water-soluble acrylic copolymer dispersion. This specialized polymer is valued for its excellent film-forming, binding, and thickening properties, making it a versatile component in advanced industrial formulations. It is primarily utilized in the production of high-quality coatings, adhesives, and sealants where durability, clarity, and water resistance are critical.

Application

• Water-Based Industrial Coatings: Acts as a primary film-forming agent and binder, providing excellent gloss, adhesion, and weatherability for metal, wood, and plastic substrates.
• Pressure-Sensitive Adhesives (PSAs): Used as a key component to formulate adhesives with balanced tack, peel strength, and shear resistance for labels and tapes.
• Textile Finishes and Binders: Imparts durable hand feel, stiffness, and wrinkle resistance to fabrics and non-woven materials.
• Paper and Paperboard Coatings: Enhances surface strength, printability, and water resistance in functional paper coatings.
• Construction Chemicals: Serves as a redispersible powder or liquid additive in cementitious mortars, tile adhesives, and sealants to improve flexibility and adhesion.
• Leather Finishing: Provides a flexible, clear topcoat that offers protection and an enhanced aesthetic finish.
• Personal Care & Cosmetics: Functions as a film former and thickener in hair styling gels, mousses, and sunscreens.
