Abstract
The method for forming a mold-release coating on a mold surface includes two basic steps: (a) providing a base coat of material on the mold surface and (b) electrostatically depositing a release powder onto the base coat of material. The base coat of material has a surface which is capable of accepting and retaining the release powder. Upon deposition of the release powder, the release powder embeds the base coat of material thereby forming a mold-release coating. The base coat may be a wax or a solvent base wax.
