Description

2-Butenedioic Acid (Z)-, Polymer With 2-Propenoic Acid, Potassium Salt is a water-soluble polycarboxylate copolymer, specifically the potassium salt of a maleic acid-acrylic acid copolymer. This product is engineered to function as a highly effective dispersant and scale inhibitor, offering superior performance in aqueous systems. It is a critical component for industries requiring advanced water treatment, detergent formulation, and mineral processing, where it prevents precipitation and stabilizes particulate suspensions. The compound, identified by CAS No. 66509-45-3, provides a reliable solution for managing water hardness and improving process efficiency.

Application

• Industrial Water Treatment: Primary application as a scale inhibitor and dispersant in cooling water, boiler water, and reverse osmosis systems to control calcium carbonate, sulfate, and phosphate scales.
• Detergent & Cleaning Formulations: Acts as a builder and anti-redeposition agent in liquid and powder detergents, enhancing cleaning power by sequestering metal ions and preventing soil from re-depositing on fabrics.
• Pulp & Paper Industry: Used as a dispersant in paper coating and bleaching processes to improve pigment slurry stability and process efficiency.
• Textile Processing: Serves as a dispersing agent in dyeing and printing operations to ensure uniform color application and prevent agglomeration.
• Mineral Processing: Applied as a grinding aid and dispersant to improve the efficiency of mineral slurry transport and separation.
• Construction Chemicals: Incorporated into cement admixtures and concrete formulations as a superplasticizer to improve workability and reduce water content.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals to control scale formation and improve fluid performance.
