Abstract
Curable compositions are provided comprising: The isocyanate-functional prepolymer is a reaction product of a polyisocyanate and either (i) a polyether having primary and/or secondary amino groups or (ii) a mixture of a polyether having primary and/or secondary amino groups and a polyether having hydroxyl groups. Upon curing, the compositions demonstrate a Young's Modulus less than 500 MPa at −40° C., a percent elongation greater than 200% at −40° C., and/or a glass transition temperature less than −20° C., making them ideally suited for use at extreme temperatures.
