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)(R)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)N—[R—Z]—R—[Si(Y)(R)] or a cyclic azasilane of Formula (II). Each Ris a linking group; each Ris a non-hydrolyzable group; each Z is —O— or —N(R)—; each Ris hydrogen, alkyl, aryl, arylalkylenyl, or —R—[Si(Y)(R)]; Ris a linking group that can have at least one catenated —N(R)—; each Ris 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.
