1. A method of coating an overhead conductor, comprising:
providing a coating composition formed from a first part and a second part, wherein the first part comprises a filler, an emissivity agent, and a crosslinking facilitator comprising a latent acid compound, wherein the latent acid compound comprises condensed aluminum phosphate; and wherein the second part comprises a metal silicate binder;
applying the coating composition onto an outer surface of the overhead conductor; and
curing the coating composition at a temperature of from about 15° C. to about 40° C. to form a coated overhead conductor having a cured coating on the outer surface thereof; and
wherein the composition comprises:
about 35% to about 45%, by dry weight, of the filler;
about 15% to about 22%, by dry weight, of the emissivity agent;
about 4% to about 10%, by dry weight, of the crosslinking facilitator; and
about 25% to about 40%, by dry weight, of the metal silicate binder.
