Abstract
Paintable compositions for the formation of coatings on, for example, iron-based metals that, when dry, inhibit deleterious reactions and emissions when the metal is heated to, or thermally cycled at, temperatures of about 600-900 degrees C. The preferred binder portion of the composition, which in itself provides reasonable protection when dry, consists essentially of an aqueous silica containing solution containing an aqueous alkali, together with oxides selected from the transition metals cobalt, chromium, iron, manganese, nickel, titanium, zinc and zirconium. The preferred ranges of composition are described as well as certain additives to enhance performance under various conditions. These include the use of filler materials, such as high expansion additives. The coating is useful for other metal and ceramic substrates to prevent or reduce deleterious damage to or emission from the surface at high temperatures.
