Description

2-Propenoic Acid, Polymer With Ethenylbenzene And (1-Methylethenyl)Benzene, Ammonium Salt is a water-soluble, anionic polymer dispersion widely used as a rheology modifier and thickener. This ammonium salt form offers excellent compatibility and ease of handling in aqueous systems, providing efficient viscosity control and stabilization. It is a critical raw material for formulators in the coatings, adhesives, and construction chemical industries seeking to enhance product performance and processability.

Application

• Architectural and Industrial Coatings: Acts as a primary thickener and rheology modifier in water-based paints, improving application properties, sag resistance, and film build.
• Adhesives and Sealants: Used to control viscosity, enhance stability, and improve the application characteristics of water-borne adhesive formulations.
• Construction Chemicals: Serves as a key additive in cementitious products, tile adhesives, and grouts to modify water retention, workability, and open time.
• Textile and Paper Coatings: Functions as a binder and thickener in coating formulations for textiles and paper to improve finish quality and processing.
• Personal Care Products: Employed as a stabilizer and viscosity-increasing agent in certain hair care and cosmetic gel formulations.
