Abstract

A curable composition includes a reaction product of an isocyanate component that includes one or more isocyanates, at an isocyanate index being from 90 to 150, and an isocyanate reactive component that includes a blend including from 5 wt % to 95 wt % of a first butylene oxide based polyol and from 5 wt % to 95 wt % of a second butylene oxide based polyol. The first butylene oxide based polyol has a number average molecular weight from 200 g/mol to 1,000 g/mol and a nominal hydroxyl functionality from 2 to 6. The second butylene oxide based polyol has a number average molecular weight greater than 1,000 g/mol and less than 8,000 g/mol and a nominal hydroxyl functionality from 2 to 4. The blend accounts for at least 50 wt % of a total weight of polyols in the isocyanate-reactive component.
