Description

Oxirane, Methyl-, Polymer With Oxirane, Ether With (1,2-Ethanediyldinitrilo)Tetrakis[Propanol] , Sulfate (Ester), Sodium Salt is a specialized, high-performance polymeric surfactant and dispersant. This compound is engineered to deliver superior wetting, emulsification, and stabilization properties in complex formulations. It is a critical additive for industries requiring advanced surface activity and compatibility with challenging chemical systems, including coatings, agrochemicals, and industrial cleaning. The product is supplied under CAS No. 73891-85-7.

Application

• Industrial & Architectural Coatings: Acts as a highly effective pigment dispersant and grinding aid, improving color development, gloss, and stability in water-based and solvent-based paint systems.
• Agrochemical Formulations: Used as a key component in pesticide and herbicide concentrates to enhance the dispersion and wetting of active ingredients, improving foliar coverage and efficacy.
• Industrial & Institutional (I&I) Cleaners: Provides powerful emulsification and soil suspension properties in heavy-duty alkaline and acidic cleaning formulations for hard surface cleaning.
• Textile Processing: Serves as a leveling agent, dispersant, and anti-precipitant in dyeing and finishing baths to ensure uniform color and process stability.
• Paper & Pulp Industry: Functions as a dispersant and deposit control agent in paper coating formulations and pulp processing to improve quality and machine runnability.
• Oilfield Chemicals: Employed in drilling muds and completion fluids as a rheology modifier and dispersant to control fluid properties under high-temperature, high-pressure (HTHP) conditions.
