Abstract:
A cure-on-demand, moisture-curable composition comprising:(a) a compound comprising molecules bearing reactive silane functional groups having the structure: ##STR11##wherein:moiety A is an m-valent radical selected from fluoroalkyl radicals, fluoroaryl radicals, and polymeric radicals comprising a polymer selected from polysiloxane, polyolefin, polyester, polyphosphazene, fluorosilicone, fluorinated polyacrylate, fluorinated polyether, fluorinated polyester, and derivatives and combinations thereof;p is an integer from 1 to 3;m is an integer greater than or equal to 1;each R.sup.1 is individually selected from alkyl radicals and acyl radicals;each R.sup.2 is individually selected from hydrogen, alkyl radicals, acyl radicals and aryl radicals; andG is an optional linking moiety which, when present, links radical A to the reactive silane functional groups; and(b) an acid generating material that is free of ammonium salt and that liberates an acid that is capable of curing the moisture-curable composition;wherein the reactive silane functional groups are the only acid curable groups present in the composition and wherein average reactive silane functionality of the moisture-curable composition is greater than two.
