Description

Butanedioic Acid, Methylene-, Polymer With 1,3-Butadiene, Ethenylbenzene And 2-Propenamide, Ammonium Salt is a specialized ammonium salt of a synthetic copolymer, engineered to deliver superior performance as a rheology modifier and stabilizer in aqueous systems. This product is valued for its ability to provide excellent thickening, suspension, and water retention properties, making it a critical component in formulations requiring precise viscosity control. It is primarily sought after by manufacturers in the coatings, adhesives, construction chemicals, and personal care industries for developing high-performance, stable products.

Application

• Coatings & Paints: Acts as a highly efficient thickener and rheology modifier in water-based architectural and industrial paints, improving anti-sag properties and application feel.
• Adhesives & Sealants: Provides excellent thickening and stabilization in water-based adhesive formulations, enhancing open time and bond strength.
• Construction Chemicals: Used in cement-based tile adhesives, grouts, and self-leveling compounds to improve water retention, workability, and sag resistance.
• Personal Care: Serves as a stabilizer and viscosity-increasing agent in lotions, creams, and hair care products, creating smooth textures.
• Textile & Paper Coatings: Functions as a binder and thickener in coating formulations for textiles and paper to improve finish quality and processing.
• Industrial Cleaners: Utilized as a thickening agent in liquid soaps and cleaning gels to stabilize active ingredients and control viscosity.

Quality Control

Our production of this copolymer ammonium salt adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including viscosity, solids content, pH, and ionic character. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee the product meets your specific formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent moisture absorption and caking. Keep away from incompatible materials such as strong oxidizing agents.
