Description

2-Propenoic Acid, Polymer With Methyl 2-Propenoate, Ammonium Salt is a water-soluble, anionic polyacrylate copolymer supplied as an ammonium salt. This polymer is valued for its excellent film-forming, binding, and dispersing properties in aqueous systems. It is a critical raw material for formulators in the coatings, adhesives, and construction chemical industries seeking to enhance performance while meeting environmental and regulatory standards.

Application

• Water-Based Paints & Coatings: Acts as a primary binder and film-former, providing excellent adhesion, scrub resistance, and durability.
• Adhesives & Sealants: Used as a key component in pressure-sensitive adhesives (PSAs) and construction sealants for its cohesive strength and tack.
• Construction Chemicals: Serves as a redispersible polymer powder (RDP) in cementitious tile adhesives, self-leveling compounds, and exterior insulation finishing systems (EIFS) to improve flexibility and water resistance.
• Textile & Leather Processing: Functions as a finishing agent and binder for pigments and dyes, enhancing color fastness and hand feel.
• Paper Coating: Improves surface strength, printability, and gloss as a component of coating formulations.
• Personal Care & Cosmetics: Utilized as a film-forming agent and thickener in hair styling gels, mousses, and skin care products.

Quality Control

Our production of 2-Propenoic Acid, Polymer With Methyl 2-Propenoate, Ammonium Salt adheres to strict quality management protocols. Each batch is tested against stringent in-house specifications for critical parameters such as solids content, viscosity, pH, and residual monomers to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these results are available upon request.

Storage

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