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 (R 6 ) 2 N—[R 4 —Z] r —R 4 —[Si(Y) p (R 5 ) 3-P ] or a cyclic azasilane of Formula (II). Each R 4 is a linking group; each R 5 is a non-hydrolyzable group; each Z is —O— or —N(R 6 )—; each R 6 is hydrogen, alkyl, aryl, arylalkylenyl, or —R 4 —[Si(Y) p (R 5 ) 3-P ]; R 7 is a linking group that can have at least one catenated —N(R 8 )—; each R 8 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. |
