Abstract: The composition includes a polyorganosiloxane and an amino-functional silane. The polyorganosiloxane has divalent units represented by Formula (I) and greater than two —Si(Y)p(R)3-P groups, in which each R is a non-hydrolyzable group; each Y is a hydrolysable group; and p is 1, 2, or 3. The composition further includes an amino-functional silane represented by (R6)2N—[R4—Z]r—R4—[Si(Y)p(R5)3-P] or a cyclic azasilane of Formula (II). Each R4 is a linking group; each R5 is a non-hydrolyzable group; each Z is —O— or —N(R6)—; each R6 is hydrogen, alkyl, aryl, arylalkylenyl, or —R4—[Si(Y)p(R5)3-P]; R7 is a linking group that can have at least one catenated —N(R8)—; each R8 is hydrogen, alkyl, or alkenyl, which may be substituted by an amino group; each Y is a hydrolyzable group; r is 0, 1, 2, or 3; and p is 1, 2, or 3. A method of using the composition to make a coated article is also described.

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.
