Abstract
A protective coating which imparts non-stick and abrasion resistant properties, as well as hydrophobic properties to an inorganic article, the coating being the composition product between hydroxyl groups on the surface of the inorganic article and a composition comprising a silane, a metal alkoxide and an acidified aqueous mixture of a lower alkanol. The silane content is at least 50% of the total sum of the silane plus the metal alkoxide. The metal alkoxide is at least 5% and preferably 10% of the total sum of the silane plus the metal alkoxide.
