Abstract: A formable multi-layered composite comprising in sequence a clear polymeric layer, a metal layer, and a protective layer is disclosed. The polymeric layer including at least one member selected from the first group consisting of polycarbonate, PETG, PCTG polystyrene and polyurethane. The metal layer contains at least one member selected from the group consisting of titanium, aluminum, copper, silver, chromium, zirconium, tin, indium and their alloys. The protective layer that contains an aliphatic polyurethane dispersion based on at least one member selected from among polycarbonate polyol and polyether polyol protects the metal layer during handling and use in the context of FIM.

Abstract: Metallic fillers are provided which are stabilized against corrosion. The metallic fillers are stabilized by treating the surface of the filler particles wtih a triazole, preferably an aromatic triazole. This may be accomplished either by pretreating the filler with a solution of the triazole, or by adding the triazole to a polymeric composition containing a metallic filler.Polymeric compositions are further provided, e.g. compositions for microwave absorption, comprising a polymeric binder, a metallic filler and a triazole.
