An ambient curable coating composition includes a mixture of components comprising a polysiloxane having a Mw of at least 10,000 as determined by gel permeation chromatography using a polystyrene standard, (b) an alkoxy functional polysiloxane, and (c) an inorganic corrosion inhibitor, a method of preparing a corrosion resistant coating comprising (i) applying the coating composition to a substrate and (ii) curing component (b) at ambient conditions; and a substrate at least partially coated with the coating composition.

Ambient cure high temperature protective coating

A sprayable polymer dispersion includes (a) a room temperature vulcanizing (RTV) silicone polymer, (b) a poly siloxane, (c) an insulating agent and (d) an organic carrier in which components (a), (b), and (c) are suspended. Also included in the present invention is a method of producing a corrosion resistant coating on a substrate comprising spraying the polymeric dispersion onto at least a portion of a substrate and moisture curing each of components (a) and (b) to form a monolithic coating on the substrate, as well as a substrate at least partially coated with the sprayable polymer dispersion.
