Silane compositions are described which comprise (A) a silane coupling agent; and (B) a tris(silylorgano)amine or alkane characterized by the formulaeorwherein each R is independently an alkyl, alkoxyalkyl, aryl, aralkyl or cycloalkyl group of less than 20 carbon atoms; R1 is a divalent hydrocarbon or polyether group of less than 20 carbon atoms; and R2 is a functional group represented bywherein n is from 0 to 20 and X is selected from the group consisting of amino, amido, hydroxy, alkoxy, halo, mercapto, carboxy, acyl, vinyl, allyl, styryl, epoxy, isocyanato, glycidoxy, and acryloxy groups. The silane compositions of the present invention are adhesive compositions providing improved bonding of surfaces such as glass, metal and metal oxides to thermosetting resins. The silane compositions also exhibit improved moisture resistance. The silane compositions are particularly useful as adhesives in preparing multi-layer laminates such as printed circuit boards. |
