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