Release Coating Composition and Method of Forming the Same

A method of coating a substrate in a release coating process, said method comprising the steps of:

• A. polymerizing a siloxane having units of the chemical formula (SiO4/2)(RaRb2SiO1/2)x wherein Ra is selected from the group of an alkyl moiety having from 1 to 6 carbon atoms, an alkenyl moiety having from 2 to 6 carbon atoms, and an alkynyl moiety having from 2 to 6 carbon atoms, Rb is selected from the group of an alkyl moiety having from 1 to 6 carbon atoms, an aryl moiety, an alkoxy moiety, an acrylate moiety, and a methacrylate moiety, and x is a number from 1.05 to less than 4, with a cyclic polysiloxane in the presence of a polymerization catalyst to form an aerosol suppressant having more than one SiO4/2 unit;
• and
• B. combining the aerosol suppressant and a curable polysiloxane to form a release coating composition;
• and
• C. applying the release coating composition to the substrate in the release coating process.
