A method of producing a silica-based superhydrophilic film. A coating formulation is provided, where the coating formulation includes an alkali metal silicate having a substantial portion of water removed therefrom, where the alkali metal silicate has a formula of M.sub.2O.Math.nSiO.sub.2, and where M represents an alkali metal and n is a positive real number greater than zero. Furthermore, the coating formulation and an alcohol including a curing agent are mixed, where the curing agent includes an acid or an alkaline earth metal halide. Additionally, the coating formulation is dried to form the silica-based superhydrophilic film. Furthermore, a silica-based superhydrophilic film is produced according to such a method, where the silica-based superhydrophilic film includes an amine stabilizer.

A composition based on a certain chromium-free silicate-based binder is described. The composition is an aqueous solution of lithium-doped potassium silicate in combination with an aluminum or aluminum alloy powder, zinc powder or a combination thereof. The coatings of the present invention are capable of achieving a full cure at temperatures as low as 350-450 degrees F. by the inclusion of a colloidal solution of a nano-sized ceria, thus making the coatings especially suitable for application on temperature sensitive base materials.

Compositions including a filler, an emissivity agent, a crosslinking facilitator, and a metal silicate binder are disclosed. The compositions can be curable at ambient conditions. Methods of coating overhead conductor and power transmission line accessories with such coating compositions are also disclosed.
