Claim:
A method of forming an anti-fog or anti-frost coating on at least a portion of a substrate, the method comprising: treating, prior to application of the anti-fog or anti-frost coating, at least a portion of the substrate with a solution consisting essentially of a first silane in water; preparing a mixture of: i) a first component comprising about 46% diacetone alcohol, about 4% N-methyl Pyrrolidone, about 4% t-butanol, about 8% Cyclohexane, about 6% 2,4-pentanedione, and about 2% Aromatic 150; and ii) a second component comprising about 66% polyisocyanate, about 1% free monomeric isocyanates, about 11% xylene, about 11% n-butyl acetate, and about 11% toluene; wherein the mixture ratio of the first component to the second component is about 100:about 30-33; adding a second silane to the mixture, wherein the second silane is different than the first silane; applying the mixture to the substrate; and curing the substrate.
