Abstract
A method for imparting corrosion resistance to a metal substrate comprising coating said substrate with a moisture-curable silicone composition is disclosed. The composition consists essentially of a tetrafunctional or hexafunctional silicone polymer (I) which is modified with a liquid organohydrogenpolysiloxane (II) such that, when the functional groups of (I) are alkoxy radicals, the organohydrogenpolysiloxane contains at least 4 silicon hydride groups per molecule and when the functional groups of (I) are oxime groups, the organohydrogenpolysiloxane contains at least 5 silicon hydride groups per molecule.
