Description

2-Butenedioic Acid (E)-, Polymer With 1,3-Butadiene And Ethenylbenzene, Sodium Salt is a high-performance, water-soluble polymer derived from maleic acid, butadiene, and styrene. This specialized copolymer is engineered to deliver superior performance as a dispersant, scale inhibitor, and rheology modifier in demanding aqueous systems. It is a critical raw material for formulators in the water treatment, construction, and coatings industries seeking to enhance product stability and efficiency.

Application

• Industrial Water Treatment: Primary application as a highly effective dispersant and antiscalant for cooling water, boiler water, and reverse osmosis (RO) systems to control calcium carbonate, sulfate, and phosphate scales.
• Construction Chemicals: Key additive in cement admixtures and gypsum-based plasters to improve workability, reduce water content, and enhance the dispersion of solid particles.
• Paints & Coatings: Utilized as a pigment dispersant and grinding aid in water-based architectural and industrial coatings to ensure color uniformity, gloss, and long-term stability.
• Detergents & Cleaners: Acts as a builder and anti-redeposition agent in liquid and powder detergent formulations to improve cleaning efficacy and prevent soil from re-adhering to fabrics.
• Paper & Pulp Industry: Employed as a dispersant and retention aid in paper coating formulations and process water systems.
• Oilfield Chemicals: Used in drilling muds and production chemicals as a rheology modifier and scale inhibitor.
