Abstract
The present invention is directed to a method for applying to a substrate having a faying surface, a polysiloxane-containing coating, preferably a polysiloxane(amide-ureide) coating capable of inhibiting corrosion as well as the accumulation of ice. One embodiment of the present invention is directed to a polysiloxane(amide-ureide) that forms a durable, long lasting, anti-corrosive and anti-ice coating when directed to a substrate faying surface.
