Description

2-Propenoic Acid, 2-Methyl-, Polymer With Ethyl 2-Propenoate, Ammonium Salt is a water-soluble acrylic copolymer supplied as an ammonium salt, offering excellent film-forming, binding, and thickening properties. This polymer is valued for its ability to enhance adhesion, provide water resistance, and modify rheology in aqueous formulations. It is a critical raw material for manufacturers in the coatings, adhesives, construction chemicals, and textile processing industries seeking high-performance, environmentally compliant additives.

Application

• Architectural and Industrial Coatings: Acts as a primary binder or co-binder in water-based paints, providing excellent scrub resistance, adhesion to various substrates, and durability.
• Adhesives and Sealants: Used as a film-forming agent and tackifier in pressure-sensitive adhesives (PSAs) and construction sealants, improving cohesive strength and water resistance.
• Construction Chemicals: Serves as a key additive in cementitious mortars, tile adhesives, and self-leveling compounds to improve workability, reduce water absorption, and enhance flexural strength.
• Textile Finishing: Employed as a non-yellowing binder and hand modifier for fabric coatings, pigment printing, and back-coating applications.
• Paper and Paperboard Coatings: Functions as a binding agent for pigments and fillers, improving surface strength, printability, and water holdout.
• Personal Care and Cosmetics: Utilized as a film former and thickener in hair styling gels, mousses, and skin care products, providing flexible hold and a non-tacky feel.

Quality Control

Our production of Ammonium Acrylate Copolymer adheres to strict quality management protocols. Each batch undergoes rigorous testing for critical parameters including solids content, viscosity, pH, and mechanical stability to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting full specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

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 absorption of atmospheric moisture, which can alter physical properties. Keep away from incompatible materials such as strong oxidizing agents.
