Curable polysiloxane coating composition |
| 摘要 |
A curable composition comprises (a) at least one polydiorganosiloxane, fluorinated polydiorganosiloxane, or combination thereof comprising reactive silane functionality comprising at least two hydroxysilyl moieties; (b) at least one polydiorganosiloxane, fluorinated polydiorganosiloxane, or combination thereof comprising reactive silane functionality comprising at least two hydrosilyl moieties; and (c) at least one base selected from amidines, guanidines, phosphazenes, proazaphosphatranes, and combinations thereof; wherein at least one of the components (a) and (b) has an average reactive silane functionality of at least three. |

1. A coating process comprising
(a) providing a curable polysiloxane composition comprising
(1) at least one polydiorganosiloxane, fluorinated polydiorganosiloxane, or combination thereof comprising reactive silane functionality comprising at least two hydroxysilyl moieties,(2) at least one polydiorganosiloxane, fluorinated polydiorganosiloxane, or combination thereof comprising reactive silane functionality comprising at least two hydrosilyl moieties, and(3) at least one base selected from amidines, guanidines, phosphazenes, proazaphosphatranes, and combinations thereof,wherein at least one of said components (1) and (2) has an average reactive silane functionality of at least three;
(b) providing at least one substrate having at least one major surface; (c) applying said curable polysiloxane composition to at least a portion of at least one said major surface of said substrate; and (d) allowing or inducing said curable polysiloxane composition to cure to form a release coating. |
