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.

Sprayable silicone polymer dispersion

Disclosed is a pretreatment composition containing (a) a Group IIIB metal, a Group IVB metal, or combinations thereof; and (b) a compound containing at least six phosphorus-containing acid groups or salts thereof; wherein the molar ratio of (a) to (b) is at least 3:1. Also disclosed are methods of treating a substrate with the pretreatment composition and substrates treated with the pretreatment composition.
