Abstract
The present disclosure provides sol-gel films and substrates, such as vehicle components, having a sol-gel film disposed thereon. At least one sol-gel formulation has about 10 wt % or less water content based on the total weight of the sol-gel formulation and comprises an organosilane, a metal alkoxide, an acid stabilizer, and an organic solvent. At least one vehicle component comprises a sol-gel coating system comprising a metal substrate and a sol-gel formulation disposed on the metal substrate. The sol-gel formulation has about 10 wt % or less water content based on the total weight of the sol-gel formulation and comprises an organosilane, a metal alkoxide, an acid stabilizer, and an organic solvent.
