Production of ceramic molds, art (modeling, sculpting) production, and production of prosthetics and orthotics. High whiteness, good workability, and water absorption. There are grades such as Special Grade and Grade A, but basically, the higher the grade, the higher the strength and whiteness after hardening. The amount of water to be mixed also differs, so please read the following explanation before use. If you would like to know more about the product, please contact the manufacturer directly. Physical Properties (Manufacturer's Announcement) 　Mixing water (per 1kg of powder): 720ml 　Pouring start time: 9 minutes 　Setting time: Initial set 14 minutes, Final set within 35 minutes 　Tensile strength (after 2 hours): 1.3MPa 　Setting expansion rate: 0.12% Pouring start time: Plaster added 1 minute + standing in water 1 minute + stirring time 7 minutes = 9 minutes Experienced User Advice: However, the above is only a guideline. It varies depending on the temperature, humidity, storage conditions of the plaster after opening, and how it is stirred. When dissolving plaster, always add the plaster to the water. Adding water to the plaster may cause lumps (partial clumps) depending on the amount, which may lead to hardening failure. Plaster is susceptible to moisture. We cannot accept refunds or returns due to factors such as the customer's management environment after opening or operational errors. Please understand.
