Abstract
An improved coating comprising a coating on a substrate is described. The coating comprises a crosslinked polymeric material derived from an alkine-bridged bis-(aminosilane) or comprising a mixture of the alkine-bridged bis-(amino-silane) and an epoxysilane. The alkine bridged bis-(aminosilane) may have the general formula: ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 are independently selected from alkyl groups of 1 to 4 carbon atoms or phenyl groups, PA1 R.sup.4 is selected from hydrogen, phenyl groups, and alkyl of from 1 to 4 carbon atoms, and PA1 n is 1, 2, 3 or 4, PA1 p is 2, 3 or 4, PA1 q is 0 or 1, PA1 o is 0 or 1, and PA1 m is 1, 2, 3 or 4, wherein q plus m is 1 or 2, o is 1 only when all aminosilane groups are bonded to the other alkine groups, and when p is 4, both m and o are zero, or preferably EQU [R.sup.1 OR.sup.2 OR.sup.3 O--Si--(CH.sub.2)n--NH].sub.2 --(C.sub.m H.sub.2m) PA1 wherein R.sup.1, R.sup.2, and R.sup.3 are independently selected from aliphatic groups or aromatic groups, and PA1 n is 1, 2, 3 or 4, and PA1 m is 1, 2, 3 or 4. The alkine bridged bis-(aminosilane) is itself a novel compound. A novel coating composition comprises A coating composition compris…
