Polyurethane composition

Abstract

A polyurethane composition includes from 50 wt % to 98 wt % of an isocyanate component, based on a total weight of the polyurethane composition, the isocyanate component including, from 7 wt % to 55 wt % of a first isocyanate-terminated prepolymer derived from a siloxane-caprolactone block copolymer polyol, based on a total weight of the isocyanate component, and from 45 wt % to 93 wt % of a second isocyanate-terminated prepolymer derived from a polyester polyol, based on the total weight of the isocyanate component. The polyurethane composition further includes from 2 wt % to 50 wt % of an isocyanate-reactive component, based on the total weight of polyurethane composition, the isocyanate-reactive component including a chain extender.
