Description

Butanedioic Acid, Methylene-, Polymer With 1,3-Butadiene And Ethenylbenzene, Sodium Salt is a high-performance, water-soluble polymeric dispersant and rheology modifier. This specialized copolymer is engineered to provide superior stabilization and viscosity control in complex aqueous and solvent-based systems. It is essential for manufacturers in the coatings, adhesives, construction chemicals, and textile processing industries seeking to enhance product performance and process efficiency.

Application

• Coatings & Inks: Acts as a highly effective dispersant and stabilizer for pigments and fillers in water-based and solvent-borne formulations, improving color strength, gloss, and preventing settling.
• Construction Chemicals: Used as a superplasticizer and water-reducing agent in cement and concrete admixtures to improve workability, strength, and durability.
• Adhesives & Sealants: Functions as a rheology modifier and tackifier, providing controlled viscosity and enhanced bonding properties.
• Textile Processing: Serves as a dye dispersant and leveling agent, ensuring uniform color uptake and fastness on synthetic and blended fabrics.
• Ceramic & Clay Processing: Employed as a deflocculant to reduce the water content in slurries, improving casting rates and green strength.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as a fluid loss control additive and shale stabilizer.
• Industrial Cleaners: Enhances the suspension of dirt and particulates in liquid cleaning formulations, preventing redeposition.
• Paper Coating: Improves the dispersion of coating pigments like calcium carbonate and kaolin, leading to a smoother, more uniform paper surface.
