Abstract:
A substrate having an essentially tack-free adherent coating thereon which comprises a moisture curable polymer composition comprising:a) a polydiolefin polymer containing olefinic unsaturation in either the main polymer backbone or in pendent side chains; or a loop polymer having a polymeric backbone including a plurality of olefinic groups which have been converted to closed loops by reaction with difunctional organic compounds reactive with the olefinic groups, the olefinic groups from which the loops are formed being either present within the backbone and/or pendent from the backbone, with the proviso that when said polydiolefin polymer is used, said composition additionally comprises polysiloxane terminated with hydrolyzable groups; and b) a silicon cross-linking compound containing at least one easily hydrolysed substituent and at least one hydride substituent, which has been exposed to moisture to cross link said composition.
