A composite sheet is manufactured by depositing a multi-layer coating on the outer surface of a substrate, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a polymerizable composition that includes a olefin group and a moisture curable group, such as an isocyanate or silane group. After the precursor is applied, the composite sheet is exposed to beam radiation or plasma discharge, ozone, and moisture, which respectively promote polymerization and curing at different sites of the precursor. The function of the cured polymeric layer preferably includes protecting the metal layer from corrosion. The amenability of the isocyanate or silane functionality to moisture-promoted coupling promotes substantially full conversion and curing of the precursor, even of portions of the substrate that are geometrically shadowed from incident beam radiation. |
