Patent attributes
A water-soluble polymer coating for application to electrical wiring used in aircraft and other electrical structures is provided. The coating includes a water-soluble polymer such as polyvinyl acetate, polyvinyl alcohol, and methyl cellulose which is dissolved in water to form a solution. The solution may be applied to electrical wiring during manufacturing and dried to a film such that if the wire becomes damaged and exposed to water, a protective water-insoluble deposit is formed on the wiring. Alternatively, the solution may be applied to wiring which is already damaged to form a protective water-insoluble deposit.
