Silicone release coating compostions

A curable silicone release coating composition obtained by a method comprising homogeneously mixing:

• (A) an organopolysiloxane containing at least two alkenyl groups per compound;
• (B) an organohydrogensilicon compound;
• (C) an inhibitor having a boiling point of up to 130.degree. C. at atmospheric pressure selected from the group consisting of acetylenic alcohols and silylated acetylenic alcohols;
• (D) an inhibitor having a boiling point of at least 170.degree. C. at atmospheric pressure selected from the group consisting of vinylcyclosiloxanes, acetylenic alcohols, and silylated acetylenic alcohols;
• (E) a platinum group metal-containing catalyst;
• and optionally (F) a diluent.

A method of making a coated article, the method comprising:

• (I) applying a curable silicone coating composition on the surface of a substrate wherein the coating composition is prepared by homogeneously mixing:
• (A) an organopolysiloxane containing at least two alkenyl groups per compound;
• (B) an organohydrogensilicon compound;
• (C) an inhibitor having a boiling point of up to 130.degree. C. at atmospheric pressure selected from the group consisting of acetylenic alcohols and silylated acetylenic alcohols;
• (D) an inhibitor having a boiling point of at least 170.degree. C. at atmospheric pressure selected from the group consisting of vinylcyclosiloxanes, acetylenic alcohols, and silylated acetylenic alcohols;
• (E) a platinum group metal-containing catalyst;
• and optionally (F) a diluent;
• and
• (II) exposing the coating and the substrate to an energy source selected from the group consisting of (i) heat and (ii) actinic radiation in an amount sufficient to cure the coating.
