Method of bonding a window to a substrate using a silane functional adhesive composition

摘要

The invention is an adhesive composition comprisinga) i) a trialkoxysilane functional polyether or polyurethane wherein the polyether or polyurethane has a weight average molecular weight of 6000 or greater and a dialkyltin carboxylate or dialkyltin alcoholate; orii) a dialkoxysilane functional polyether or polyurethane and a dialkyltin alcoholate; andb) a primary or secondary amino straight chain alkyl trialkoxysilane;wherein the dialkyltin carboxylate or dialkyltin alcoholate is present in an effective amount to facilitate bonding of the adhesive to a substrate of from about 0.1 to about 1.0 percent by weight based on the weight of the adhesive and the primary or secondary amino straight chained alkyl trialkoxysilane is present in an amount which is effective to facilitate bonding of the adhesive to a substrate wherein the amount is from about 0.5 to about 1.2 percent by weight.
