Abstract (en)
[origin: EP2133165A1] Process for casting copper and copper alloys, comprises: providing a mold; applying a coating on the inner wall of the mold, where the coating comprises at least one inorganic oxide and a binder; solidifying the coating; filling a melt of copper or copper alloy into the mold, where the mold is heated to 60-200[deg] C before the filling process; and extracting the resulting cast from the mold. Independent claims are included for: (1) reusable molds hydrophobic coating, produced from a coating comprising at least one inorganic oxide, at least 1 wt.% of polysiloxane and a binder; and (2) a mold with extended stable time comprising a hydrophobic coating, where the mold is temperature controlled at 60-200[deg] C.
