Description

2,5-Furandione, Polymer With Ethenylbenzene, 2-Butoxyethyl Ester, Ammonium Salt is a specialized ammonium salt of a styrene-maleic anhydride copolymer derivative, designed to offer enhanced solubility and functionality in aqueous systems. This product matters for formulators seeking stable, water-compatible polymeric additives with dispersing and emulsifying properties. Key industries that need it include coatings, adhesives, inks, and textile processing, where it acts as a rheology modifier, dispersant, or compatibilizer.

Application

• Coatings & Paints: Acts as a pigment dispersant and rheology modifier in water-based architectural and industrial coatings.
• Adhesives & Sealants: Used as a stabilizer and tackifier in aqueous adhesive formulations.
• Printing Inks: Serves as a grinding aid and stabilizer for pigment dispersions in water-based ink systems.
• Textile Processing: Functions as a dye dispersant and leveling agent to improve color uniformity.
• Paper Coatings: Enhances pigment binding and improves coating smoothness and gloss.
• Construction Chemicals: Utilized as a plasticizer and water-retention agent in cementitious mixtures and mortars.
• Industrial Cleaners: Acts as a surfactant and soil suspending agent in alkaline and neutral cleaning formulations.
