The invention pertains generally to providing an increased amount of both hydrophobicity and oleophobicity by the combination of at least one silane and at least one siloxane, the silane preferably being a trialkoxysilane of Formula (I) and at least one polysiloxane of Formula (II), the combined composition of silane and polysiloxane having no added perfluorinated compounds. The invention further includes an ability to darken the color of the surface to which it is applied by at least 5, preferably 10 “L” units, giving the surface more of a “wet” look.

The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.
