An anti-corrosive sol-gel that is a combination of an organometallic salt, an organosilane, and a borate, phosphate, or zinc functional component. The organosilane component may be selected from a large group of equivalent compounds but is preferably an alkoxyzirconium salt, and most preferably Zr (IV) n-propoxide. The organosilane may also be selected from a large group of equivalent compounds, but is preferably 3-glycidoxypropyltrimethoxysilane (GTMS). Combination of the components takes place in the presence of an organic catalyst, preferably acetic acid. |
