Description

2-Butenedioic Acid (2E)-, Polymer With Methyloxirane And Oxirane is a high-performance polymeric surfactant and dispersant derived from maleic acid, propylene oxide, and ethylene oxide. This copolymer is engineered to provide exceptional stabilization, wetting, and viscosity control in complex aqueous and solvent-based systems. It is a critical raw material for formulators in the coatings, construction chemicals, and agrochemical industries seeking to enhance product performance and process efficiency. The compound is supplied under CAS No. 68400-72-6.

Application

• Coatings & Inks: Acts as a highly effective pigment dispersant and grinding aid in water-based and solvent-based paints, improving color strength, gloss, and stability.
• Construction Chemicals: Used as a superplasticizer and water-reducing agent in concrete admixtures to improve workability and final strength.
• Agrochemical Formulations: Serves as a key component in suspension concentrates (SC) and wettable powders (WP) for stabilizing active ingredients and improving sprayability.
• Industrial Cleaners & Detergents: Functions as a scale inhibitor and dispersant in liquid formulations to prevent redeposition of soils and inorganic salts.
• Textile & Leather Processing: Employed as a leveling agent and dye dispersant to ensure uniform color application and processing aid.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals as a rheology modifier and dispersant for clays and solids.
