Description

Alcohols, C16-18, Ethoxylated, Reaction Products With 1,6-Diisocyanatohexane is a specialized nonionic surfactant and polymeric material formed by the reaction of ethoxylated C16-18 fatty alcohols with 1,6-diisocyanatohexane (HDI). This chemistry matters because it creates a versatile product with unique emulsifying, dispersing, and film-forming properties, offering enhanced performance over simpler ethoxylates. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in textile auxiliaries and industrial cleaning applications, where it acts as a rheology modifier, stabilizer, or compatibilizer.

Application

• Coatings & Paints: Used as a dispersing agent and rheology modifier in water-based and solvent-based coating systems to improve pigment wetting and stability.
• Adhesives & Sealants: Functions as a compatibilizer and viscosity control agent in polyurethane and other polymer-based adhesive formulations.
• Textile Processing: Serves as a lubricant, softener, and anti-static agent in fiber and fabric treatment processes.
• Industrial & Institutional (I&I) Cleaning: Acts as a surfactant and emulsifier in heavy-duty degreasers and cleaning concentrates.
• Polymer Production: Can be utilized as an intermediate or additive in the synthesis of polyurethanes and other specialty polymers.
• Metalworking Fluids: Employed as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic metalworking fluids.
• Leather Processing: Used in fatliquoring and finishing stages to improve softness and water repellency.
• Agricultural Adjuvants: Functions as a surfactant and deposition aid in pesticide and herbicide formulations.
