Nonaqueous sol-gel for adhesion enhancement of water-sensitive materials

A vehicle component comprising a sol-gel coating system, wherein the sol-gel system comprises:

• a metal substrate;
• and
• a sol-gel formulation comprising:
• an organosilane having at least one epoxide moiety;
• a metal alkoxide;
• an acid stabilizer;
• a corrosion inhibitor having one or more thiol moieties;
• and
• an organic solvent, wherein the sol-gel formulation has about 0 wt % to about 10 wt % water content based on the total weight of the sol-gel formulation.
