HYDROPERM Gypsum Cement is used to produce permeable plaster molds for casting of many non-ferrous metals and alloys. Molds made from conventional metal casting plasters are relatively impermeable. Properly prepared molds made with HYDROPERM Cement have a permeability range which can be varied and controlled to meet particular requirements of the various nonferrous metals and have an extremely smooth surface. |
