Description

2,5-Furandione, Polymer With Methyloxirane Polymer With Oxirane Ether With 1,2,3-Propanetriol (3:1) is a specialized polymeric surfactant and dispersant, synthesized from maleic anhydride, propylene oxide, ethylene oxide, and glycerol. This compound is valued for its excellent surface-active properties and ability to modify rheology and stability in complex formulations. It is primarily sought by manufacturers in the coatings, construction chemicals, and agrochemical industries for its performance as a pigment dispersant, grinding aid, and viscosity modifier. The product is supplied with a CAS registry number of 68834-10-6.

Application

• Pigment & Filler Dispersion in Paints & Coatings: Acts as a highly effective grinding aid and stabilizer for inorganic pigments (e.g., titanium dioxide, iron oxides) and extenders in water-based and solvent-based systems.
• Construction Chemical Additives: Used in cementitious formulations, tile adhesives, and self-leveling compounds to improve workability, reduce water demand, and enhance dispersion of solid particles.
• Agrochemical Formulations: Serves as a dispersant and stabilizer in suspension concentrates (SC) and wettable powders (WP) for pesticides and herbicides.
• Industrial & Institutional Cleaners: Functions as a surfactant and dispersant in liquid detergent formulations, aiding in soil suspension and preventing redeposition.
• Textile & Leather Processing Auxiliaries: Employed in dyeing and finishing processes to improve dye dispersion and leveling.
• Paper Coating Additives: Enhances the dispersion of clay and calcium carbonate in coating slips for improved paper gloss and printability.
