Description

2-Butenedioic Acid (Z)-, Monomethyl Ester, Polymer With Ethenylbenzene And 2,5-Furandione, Ammonium Salt is a specialized ammonium salt of a maleic acid-based copolymer, designed for high-performance applications requiring water solubility and ionic functionality. This product matters for its role as a versatile dispersant, scale inhibitor, and rheology modifier in demanding aqueous systems. Key industries that need this polymer include water treatment, coatings and inks, construction chemicals, and textile processing, where it enhances stability and process efficiency.

Application

• Water Treatment: Acts as a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems.
• Industrial Coatings & Inks: Serves as a pigment grinding aid and stabilizer in water-based formulations, improving color development and preventing settling.
• Construction Chemicals: Used as a superplasticizer and water-reducing agent in cement and concrete admixtures to enhance workability and strength.
• Textile Processing: Functions as a dye dispersant and leveling agent, ensuring uniform color uptake and fastness.
• Paper Manufacturing: Employed as a retention aid and dispersant in pulp slurries to improve sheet formation and drainage.
• Detergents & Cleaners: Enhances the suspension of soil and prevents redeposition in liquid and powder detergent formulations.
• Oilfield Chemicals: Used in drilling muds and completion fluids as a rheology modifier and clay stabilizer.
• Agricultural Formulations: Aids in the dispersion and stabilization of active ingredients in suspension concentrates (SC) and wettable powders (WP).

Quality Control

Our production of 2-Butenedioic Acid (Z)-, Monomethyl Ester, Polymer With Ethenylbenzene And 2,5-Furandione, Ammonium Salt adheres to a strict quality management system. Every batch undergoes rigorous testing to ensure consistent performance, including analysis of solid content, viscosity, pH, and ionic character. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product performance.
