"For example, such epoxy functional silanes are represented by the formula R3 xSi(OR4)4-x where x is an integer of 1, 2 or 3, R3 is H, an alkyl group, a functionalized alkyl group, an alkylene group, an aryl group, an alkyl ether, and combinations thereof containing from 1 to about 10 carbon atoms and having at least 1 epoxy functional group, and R4 is H, an alkyl group containing from 1 to about 5" . . . .
