Abstract
Methods are generally disclosed for forming and using a release sheet. To form the release sheet, a release coating is applied over a first surface of a base sheet. Generally, the release coating includes a fatty alcohol ester of acrylic acid and a curable monomer, and can also include a curable polymeric resin. Then, the release coating can be cured. In one particular embodiment, the release coating can be substantially free from siloxanes. The release sheet formed according to this method is also generally provided, along with methods of forming a casting sheet using the release sheet are also generally provided.
