Coating compositions comprising a polysulfide corrosion inhibitor

Abstract

The present disclosure is directed to a coating composition comprising a film-forming binder, and a corrosion inhibitor comprising a polysulfide corrosion inhibitor, wherein the polysulfide corrosion inhibitor has a passive window value measured as a solution over a substrate greater than the passive window value of a solution without the corrosion inhibitor tested over the same substrate, as measured according to the PASSIVE WINDOW TEST METHOD, and the poly sulfide corrosion inhibitor has a polarization resistance (Rp) measured as a solution over a substrate greater than the polarization resistance (Rp) of a solution without the corrosion inhibitor tested over the same substrate, as measured according to the LINEAR POLARIZATION RESISTANCE TEST METHOD.

Dependencies are inferred from the claim text.
