Description

2-Butenedioic Acid (E)-, Polymer With 1,3-Butadiene And Ethenylbenzene, Ammonium Salt is a high-performance, water-soluble polymer designed for demanding industrial applications. This specialized ammonium salt of a maleic acid copolymer offers superior functionality as a dispersant, scale inhibitor, and rheology modifier. It is essential for manufacturers in sectors requiring precise control over particle suspension and water treatment, including coatings, construction materials, and industrial water systems.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Construction Chemicals: Functions as a superplasticizer and dispersant in cement, concrete admixtures, and gypsum boards to improve workability and reduce water content.
• Paints & Coatings: Serves as a pigment dispersant and grinding aid, enhancing color development, gloss, and stability in aqueous formulations.
• Detergents & Cleaners: Used as a builder and anti-redeposition agent to improve cleaning efficiency and prevent soil from re-adhering to fabrics.
• Paper Manufacturing: Employed as a retention aid and dispersant to improve fiber and filler distribution, enhancing paper strength and quality.
• Textile Processing: Acts as a dye dispersant and leveling agent to ensure uniform color uptake and fastness.
• Ceramic & Clay Processing: Improves the plasticity and deflocculation of slurries, aiding in shaping and reducing cracking.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as a viscosifier and fluid loss control additive.
