| description | A photocurable silicone composition, a method of forming a coating from such compositions, and an article comprising a coating formed from such compositions and/or methods are shown and described herein. The photocurable silicone composition comprises (i) a vinyl functional polysiloxane; (ii) a hydride functional polysiloxane; (iii) a photoactive catalyst; and (iv) an acid-anhydride functional polysiloxane. The composition and method can be employed to process thin coatings onto paper and film substrates followed by exposure to actinic radiation at ambient conditions of temperature and atmosphere for manufacture of release liners.
L'invention concerne une composition de silicone photodurcissable, un procédé de formation d'un revêtement à partir de telles compositions, et un article comprenant un revêtement formé à partir de telles compositions et/ou procédés. La composition de silicone photodurcissable comprend (i) un polysiloxane à fonction vinyle ; (ii) un polysiloxane à fonction hydrure ; (iii) un catalyseur photoactif ; et (iv) un polysiloxane à fonction acide-anhydride. La composition et le procédé peuvent être utilisés pour le dépôt de revêtements minces sur des substrats en papier et en film, cela étant suivi d'une exposition à un rayonnement actinique dans des conditions ambiantes de température et d'atmosphère pour la fabrication de revêtements anti-adhésifs. |
