Description

Ammoniumpolymethacrylate is a water-soluble polymer salt widely used as a dispersant, thickener, and stabilizer. Its primary value lies in its ability to control rheology, prevent particle agglomeration, and enhance the stability of complex formulations. This makes it a critical additive for manufacturers in the coatings, construction, and personal care industries seeking to improve product performance and process efficiency.

Application

• Coatings & Inks: Acts as an effective dispersant and rheology modifier in water-based paints, printing inks, and industrial coatings to ensure uniform pigment distribution and optimal application viscosity.
• Construction Materials: Used as a superplasticizer and water-reducing agent in cement and concrete admixtures to improve workability and final strength.
• Personal Care & Cosmetics: Functions as a thickener, stabilizer, and film-forming agent in lotions, creams, hair gels, and sunscreen formulations.
• Ceramics & Pigments: Serves as a processing aid to disperse ceramic powders and inorganic pigments uniformly during manufacturing.
• Adhesives & Sealants: Enhances the viscosity, stability, and application properties of water-based adhesive systems.
• Textile & Paper Processing: Utilized as a sizing agent, coating additive, or processing chemical to modify surface properties and improve finish quality.

Quality Control

Our Ammoniumpolymethacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of molecular weight distribution, solids content, viscosity, and pH. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your technical requirements.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption and caking.
