Abstract
A method for forming a mold-release coating on a mold surface includes providing a coating of material on the mold surface. The coating of material has a surface which is capable of accepting and retaining a release powder. The method also includes depositing the release powder onto the coating of material. The release powder embeds the coating of material upon deposition thereby forming a mold-release coating.

A method for forming a mold-release coating on a mold surface, comprising:
- providing a coating of material on the mold surface, the coating of material having a surface which is capable of accepting and retaining a release powder;
- and
- depositing the release powder onto the coating of material, the release powder embedding the coating of material upon deposition thereby forming a mold-release coating.
A method for forming a mold-release coating on a mold surface, comprising:
- providing a coating of material on the mold surface, the coating of material having a surface which is capable of accepting and retaining a release powder;
- and
- depositing the release powder onto the coating of material, the release powder embedding the coating of material upon deposition thereby forming a mold-release coating;
- wherein the coating of material comprises a hardenable polymeric material;
- and
- wherein the hardenable polymeric material is an epoxy resin.
A method for forming a mold-release coating on a mold surface, comprising:
- providing a coating of hardened polymeric material on the mold surface, the coating of hardened polymeric material having a surface which is capable of accepting and retaining a release powder;
- and
- depositing the release powder onto the coating of hardened polymeric material, the release powder embedding the hardened polymeric material upon deposition thereby forming a mold-release coating;
- and
- conditioning the surface of the coating of material to render it capable of accepting and retaining powder.
