Abstract
A film is adhered to a metal plate of a condensing heat exchanger by a cured layer of silicone RTV elastomer to prevent corrosion of the condensing heat exchanger. A layer of solid silicon RTV elastomer including an organosilicone functional group is applied on the pretreated metal surface. The metal plate is heated and a protective film is then applied. The film is adhered to the surface of the metal sheet by curing the layer of silicone RTV elastomer with the water. The water reacts with the organosilicone functional groups on the silicone RTV elastomer layer, cross-linking the organosilicone functional groups to create an adhesive surface which adheres the film to the surface.
