ABSTRACT:
Described herein is a polyurethane sealant composition comprising (1) a urethane prepolymer having an isocyanate functionality of at least about 2.0 and a molecular weight of at least about 2,000; and (2) the reaction product of a secondary amino- or mercaptoalkoxy silane and a polyisocyanate having an average of at least one silane group and at least one isocyanate group per molecule and a molecular weight of less than about 2,000. The sealant composition of the invention is particularly useful in bonding glass to metal substrates when the glass substrate has not been primed with an application of a separate primer composition prior to the application of the sealant.
