Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate And 2-Propenenitrile, Ammonium Salt is a water-soluble, anionic acrylic copolymer supplied as an ammonium salt, offering excellent film-forming, binding, and thickening properties. This versatile polymer is engineered to provide consistent performance in demanding formulations where stability, clarity, and adhesion are critical. It is an essential raw material for manufacturers in the coatings, adhesives, and construction chemical industries seeking to enhance product durability and functionality.

Application

• Water-Based Paints & Coatings: Acts as a primary binder and film-former, providing excellent gloss, scrub resistance, and adhesion to various substrates.
• Pressure-Sensitive Adhesives (PSAs): Used as a key component in label and tape adhesives for its tackifying and cohesive strength properties.
• Construction Chemicals: Serves as a redispersible powder or liquid additive in tile adhesives, grouts, and self-leveling compounds to improve flexibility and water resistance.
• Textile & Nonwoven Binders: Provides durable binding and hand feel improvement in fabric coatings and nonwoven fabric production.
• Paper & Paperboard Coatings: Enhances surface strength, printability, and gloss in coating formulations for high-quality paper products.
• Leather Finishing: Used in topcoat formulations to impart a flexible, protective, and glossy finish.
