Zusammenfassung: | An isolator for protecting adjacently located dissimilar material substrates from galvanic corrosion. The isolator includes a backing layer having opposite major surfaces and a thickness, and an optional uncured adhesive layer having one major surface bonded to one of the major surfaces of the backing layer and another major exposed surface for being adhesively bondable to a surface of one of the dissimilar material substrates. In its cured state, the adhesive layer and the backing layer are each not permanently compressible. At least one or both of the cured adhesive layer and the backing layer is polar solvent resistant enough to prevent polar solvent transported metal ions from passing all the way through its thickness. In preferred embodiments the backing layer comprises a tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride (THV) material, and the adhesive layer comprises an epoxy resin. |
