It is used for advanced mounting, tensioner, articulator. It is recommended for those who want to work on precision modeling. It has the highest expansion coefficient of 0.12, it is not very different from cemented carbide and hard gypsum, so you can get an excellent model. It is recommended for those who had trouble working due to the large expansion rate of ordinary white Gypsum. For those who want regular white gypsum, we recommend the low-cost KOROCK 45W.
