The specific embodiment of the present disclosure provides a protective coating. An anticorrosive coating having a compact rigid molecular structure is formed by plasma polymerization coating of monomers including alicyclic epoxy structural units, and a hydrophobic coating is simultaneously formed by plasma polymerization coating on the anticorrosive coating, thus, coatings with excellent protective performance to the substrate are formed.

Two-component polycarbonate-based composite products are contemplated in which the composite is formed as the cured reaction product of a polycarbonate polyurethane dispersed within an aqueous colloid along with a coalescent agent, a secondary polymer additive dispersed within the aqueous colloid, and a secondary polymer crosslinker. The aqueous colloidal dispersion may be applied as a coating to a surface that is intended to be coated and subsequently permitted to react and dry, resulting in the formation of a coating at the location at which it is applied. The composite product may be further formulated with additional constituents to be optically clear, glossy, and/or pigmented.
