Small portions, transparent zipper bags Mixing water amount (per 1kg of powder): 420ml Pouring time: 3 minutes Start time: 10 minutes Setting time: Initial set within 10 minutes, final set within 35 minutes Tensile strength (after 2 hours): 2.5Mpa Setting expansion rate: 0.30% 1. The standard mixing water amount for pouring molding is 420ml of water per 1kg of gypsum powder. Put the prescribed amount of water into a stirring container, and add the gypsum powder while scattering it over 1 minute. After adding the gypsum powder, let it stand for 1 minute. 2. Stir with a stirring rod at a speed of about 100 times per minute for 3 minutes. Using an electric stirrer to stir evenly will give better results. Be careful as insufficient stirring will result in more water separation. 3. The gypsum will generate heat and finish setting within 35 minutes. However, since the expansion rate changes while the heat generation temperature is high, perform the demolding work after it has cooled to room temperature. [Precautions] 1. To avoid the effects of dust on the human body, wear a protective mask and protective glasses in a place with appropriate dust-proof equipment. Long-term inhalation of dust may cause inflammation and damage to the respiratory system. 2. Wear protective gloves as gypsum slurry may cause inflammation if it comes into contact with hands or skin. 3. If the gas generated by the hardening heat of gypsum comes into contact with the eyes, nose, or skin, it may cause pain and inflammation, so ventilate well and do not unnecessarily bring your face or body close. 4. Gypsum molds may break, so never enter under a mold that has been lifted. 5. Pay attention to pollution from hardened gypsum products and wastewater after use. 6. Problems may occur if different types of gypsum are mixed. 7. We cannot guarantee performance if used for purposes other than those specified. 8. After opening, seal the opened part or transfer it to a sealed container and store it away from high temperatures and humidity. 9. There is a risk of collapse if the number of stacking layers is large. [First Aid] In case of contact with eyes: Immediately flush thoroughly with water and seek medical attention. In case of contact with skin: Wash thoroughly with water and seek medical attention if necessary. In case of inhalation: Immediately move to a place with fresh air, wash the nose and mouth thoroughly with water, and seek medical attention if a large amount has been inhaled. In case of ingestion: Wash the mouth thoroughly with water and seek medical attention if a large amount has been ingested.
