Abstract: The process includes applying a first composition on at least the portion of a siliceous substrate and subsequently applying a second composition on at least a portion of the first composition. The first composition includes an amine-reactive organosilane compound that is at least partially hydrolyzed. The second coating composition includes at least one of an amino-functional silane or cyclic azasilane and a condensation-curable polyorganosiloxane having divalent units represented by formula (I). The use of the first composition to improve the durability of the second composition, a kit including the first composition and the second composition, and a coated article made by the process are also described.
