ABSTRACT:
A corrosion inhibiting, EMI/RFI shielding composition is provided comprising a polyurethane resin which comprises a hydroxy or amine functional first polymer and an isocyanate, or isocyanurate terminated second polymer, a stabilized conductive filler, and an azole. In one embodiment of the invention a composition is provided comprising a polyurethane which comprises a fluoroolefin vinyl ether and an isocyanurate, a stabilized copper powder, and a triazole selected from the group consisting of alkyl substituted aromatic triazoles and other azoles. The invention further provides a method of composition a substrate with a composition of the invention in order to provide EMI/RFI shielding and prevent corrosion, and a substrate thus coated.
