The disclosed adhesive compositions comprise (A) an isocyanate component comprising (i) an isocyanate and (ii) an isocyanate-terminated silane compound. In some embodiments, the isocyanate-terminated silane compound (ii) is a polyisocyanate and an isocyanate-reactive compound comprising a silyl group and at least one isocyanate-reactive group selected from the group consisting of -OH, -SH and -NHR wherein R represents an alkyl residue having 1 to 12 C atoms or a cycloaliphatic or aromatic residue having between 6 and 12 C atoms. In other embodiments, the isocyanate-terminated silane compound (ii) is selected from isophorone diisocyanate, m-xylylene diisocyanate, mixtures thereof, dimers thereof, trimers thereof, prepolymerized Reaction products of polyisocyanates of the group consisting of compounds and combinations thereof with isocyanate-reactive compounds comprising silyl groups and at least one isocyanate-reactive group of -NH 2 . Also disclosed are methods for preparing the disclosed two-part adhesive compositions, and methods for forming laminates comprising the two-part adhesive compositions. |
