To Use Gypsum Products Safely

Precautions for Using Gypsum

＊Avoid contact with eyes.
If powder gets into your eyes, immediately rinse with plenty of running water and seek medical advice from an ophthalmologist.
＊Avoid inhaling dust.
Handle gypsum in areas with local exhaust ventilation and wear dust masks approved by relevant authorities.
＊Gypsum is highly hygroscopic and should be protected from rain, moisture, and high humidity.
Keep it sealed before and during use and store it in a dry, cool place.
＊Avoid storing in places prone to condensation, high humidity, or direct contact with floors or walls.
＊The physical properties and usage methods listed in catalogs are for reference only and do not guarantee the product’s performance.
＊Performance cannot be guaranteed if the product is used for purposes other than those specified.
＊Be cautious of the risk of collapse when stacking multiple layers.
＊Refer to the Safety Data Sheet (SDS) for additional information.

In addition to the above, please pay attention to the following points.

●Plaster for Ceramic Molds

＊Be cautious of the risk of gypsum molds breaking and debris flying during wheel forming.

●Gypsum for Cases

＊For those with sensitive skin, apply hand cream and wear rubber gloves to avoid contact with gypsum slurry, which may cause skin irritation.
＊Avoid unnecessary contact with your face or body during gypsum’s exothermic hardening process, as the resulting gases can cause pain or inflammation when in contact with eyes, nose, or skin.
＊Be cautious of potential injuries from breakages during processing.
＊Pay attention to the environmental impact of suspended solids and pH levels in wastewater.
Consult local authorities for proper disposal procedures.
＊Different types of gypsum may have acidic or alkaline pH, and mixing them can cause issues; consult the manufacturer for guidance.

●Plaster for Industrial Models

＊For those with sensitive skin, apply hand cream and wear rubber gloves to avoid contact with gypsum slurry, which may cause skin irritation.
＊Avoid unnecessary contact with your face or body during gypsum’s exothermic hardening process, as the resulting gases can cause pain or inflammation when in contact with eyes, nose, or skin.
＊Never stand under suspended molds as they may break and cause injury.
＊Pay attention to the environmental impact of suspended solids and pH levels in wastewater.

●Gypsum for Casting and Dental Casting Investments

＊Avoid inhaling dust.
Handle in areas with local exhaust ventilation systems, and wear dust masks approved by public authorities.
Some raw materials may contain crystalline silica, which can cause lung damage such as silicosis.
＊Follow the instructions for drying molds in casting gypsum.
Inadequate removal of crystalline water may pose risks during metal casting.
＊Performance cannot be guaranteed if the product is used for purposes other than those specified.

●Dental Plaster, Dental Stone and Die Stone

＊Not for consumption.
Keep out of reach of children.
＊Be cautious of potential injuries from breakages during processing.
＊Avoid clogging of drains.
＊Performance cannot be guaranteed if used for purposes other than those specified.

●Gypsum for Building Materials

＊Gypsum hardened structures may break, so never stand under suspended hardened structures.

●Gypsum for Art Supplies

●Calcium Sulfate (Raw Gypsum)

＊For food use, adhere to the “Calcium Sulfate” standards in the Standards for Food Additives.
