Description

Butanedioic Acid, Methylene-, Polymer With 1,3-Butadiene, Ethenylbenzene And 2-Propenamide, Sodium Salt is a high-performance, water-soluble anionic copolymer designed for demanding industrial applications. This specialized polymer offers exceptional functionality as a dispersant, rheology modifier, and scale inhibitor, making it critical for process efficiency and product stability. It is primarily utilized by manufacturers in the water treatment, construction, coatings, and textile industries seeking to enhance performance and control costs.

Application

• Water Treatment: Acts as a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems to control calcium carbonate, sulfate, and phosphate scales.
• Construction Chemicals: Used as a superplasticizer and water-reducing agent in concrete admixtures to improve workability, strength, and durability while reducing water content.
• Coatings & Paints: Functions as a pigment dispersant and rheology modifier in aqueous formulations to ensure color uniformity, stability, and optimal application properties.
• Textile Processing: Serves as a dye dispersant and leveling agent to promote even dye uptake and improve color fastness on synthetic and natural fibers.
• Paper Manufacturing: Employed as a retention aid and dispersant in pulp processing to enhance filler retention, drainage, and sheet formation.
• Ceramic & Detergent: Aids in the dispersion of inorganic particles in ceramic slips and acts as a builder co-agent in detergent formulations to prevent redeposition.
