Abstract
A release coating composition and a method of forming a release coating on a bakeware substrate using the coating composition is provided. The release coating composition includes (i) an acrylic resin, (ii) an epoxy resin, and (iii) a silicone release agent. The release coating composition can be formed in two parts, a base coat composition and a top coat composition. The base coat composition may include an epoxy resin, an acrylic resin, a color additive and appropriate solvents. The top coat composition may include an acrylic resin, an epoxy resin, a silicone release agent, a silicone resin and appropriate solvents. Each of the parts can be separately applied to the bakeware substrate and heated to form a release coating. In some cases, the top coat composition alone may only be applied if fabrication of the coated substrate will not be severe.
