Abstract: A cured composition including a reaction product of a mixture that includes an isocyanate component having one or more isocyanates and an isocyanate-reactive component having a butylene oxide based polyol, which has a number average molecular weight greater than 2,000 g/mol and less than 8,000 g/mol and a nominal hydroxyl functionality from (2) to (4). At least (50) wt % of a total weight of alkylene oxides used to form the butylene oxide based polyol is butylene oxide. An isocyanate index of the mixture is from (90) to (150). The cured composition in a cured state exhibits a first tan delta peak between a first temperature range of 50° C. to 0° C. and a second tan delta peak between a second temperature range of 75° C. and 150° C.

Abstract: An epoxy composition that includes an epoxy-terminated prepolymer, an alkanolamine hardener having at least one hydroxyl group and an organometallic compound, where amine groups of the alkanolamine hardener react with epoxy groups of the epoxy-terminated prepolymer in a stoichiometric ratio to form a cured epoxy composition. The epoxy-terminated prepolymer is formed from a reaction product of an amine terminated polymeric polyol and a molar excess of epoxy groups in an epoxy monomer, relative to a molar amount of amine groups in the amine terminated polymeric polyol.
