WIPO Patent Application WO/2023/085883
Kind Code:
A1
Abstract:
The present invention relates to an isocyanate prepolymer composition and use thereof and, more particularly, to: an isocyanate prepolymer composition which is prepared by a urethane reaction of an anhydrosugar alcohol-alkylene glycol composition, a polyol composition comprising a polyether polyol, and a polyisocyanate, the anhydrosugar alcohol-alkylene glycol composition being obtained by adding an alkylene oxide to an anhydrosugar alcohol composition comprising monoanhydrosugar alcohol, dianhydrosugar alcohol, polysaccharide alcohol, polysaccharide alcohol-derived anhydrosugar alcohol, and a polymer of one or more thereof, which is eco-friendly, and which particularly can enhance tensile strength, T-peeling strength, and room temperature impact strength of an epoxy resin composition for adhesion to which an end-capped isocyanate prepolymer composition prepared using the isocyanate prepolymer composition is applied as an adhesion promoter for an epoxy resin; an end-capped isocyanate prepolymer composition using the prepolymer composition; an adhesion promoter comprising same for an epoxy resin; and an epoxy resin composition comprising the adhesion promoter and an adhesive comprising the epoxy resin composition.
