Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Methyl-2-Propenoate, Ethenylbenzene And 2-Propenoic Acid, Ammonium Salt is a specialized ammonium salt of an acrylic copolymer designed for enhanced performance in aqueous systems. This product matters for formulators seeking a stable, water-soluble polymer with excellent film-forming, binding, and thickening properties. It is primarily needed by manufacturers in the paints & coatings, adhesives, textile finishing, and paper coating industries where consistent rheology and durability are critical.

Application

• Water-Based Paints & Coatings: Acts as a key binder and rheology modifier, improving film integrity, scrub resistance, and pigment dispersion.
• Industrial & Pressure-Sensitive Adhesives: Provides strong tack, peel strength, and cohesive properties in emulsion-based adhesive formulations.
• Textile Finishing & Back-Coating: Used as a binder for non-wovens, fabric coatings, and finishes to impart stiffness, durability, and water resistance.
• Paper & Paperboard Coatings: Enhances surface strength, printability, and gloss in coating formulations for high-quality paper products.
• Construction Chemicals: Employed as an additive in cement modifiers, tile adhesives, and sealants to improve workability, adhesion, and water retention.
• Leather Finishing: Serves as a film-forming agent in topcoat formulations to provide a protective, flexible finish.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing to ensure consistency in critical parameters such as solids content, viscosity, pH, and particle size. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep containers tightly sealed when not in use to prevent moisture absorption and skin formation. Protect from freezing.
