Porcelain gypsum plaster
Porcelain gypsum is cast into molds, for reliefs, models, ornaments and reproductions of large shapes up to small highly detailed shapes.
- Easy to handle
- fast curing
- Drying and firing redundant
- Precise reproduction of details
- Surface treatment with all common paints
- Exceptionally hard and strong
This plaster is perfect for making casts in Alginate 3D-Gel.
A water-miscible super fine ceramic powder, which, after brief stirring, gives an excellent liquid ceramic mass, with high density. This material is used in casting molds, for reliefs, models, ornaments and reproductions of large shapes up to and including very small detailed shapes. Thix plaster is of course alot denser and stronger than plaster used at home.
- Mixing ratio (weight): Powder:Water = 4:1
- Density: 1.96 g/cm3
- Pot Life at 20°C: 6 minutes
- De-mould time at 20°C: 30 minutes
- Full strength after: 8 hours
- Recoatable after: 48 hours.
Measure the appropriate amount of powder and water, according to the mixing ratio. Sprinkle the porcelain plaster into the water and wait at least 20 seconds so the plaster is fully wetted. Stir vigorously without introducing too many air bubbles. Larger quantities can be mechanically mixed. Pour a thin stream and apply a thin layer to prevent air bubbles, further filling can be done at once.
After approximately 30 minutes, one can take the cured model from a dry mold (a wet mold like algiante may take longer!). The curing model heats up quickly. It is therefore recommended to place the model on e.g. wooden slats until it is completely cooled. After the omplete cure, of approximately 8 hours, you can finish the cast (painting machineing etc).
Only use clean water and materials. Take note of the work time. You can color the plaster by adding a maximum of 2%, of the water-plaster mixtures weight with Color paste for acrylic resin from our webshop.
Example of Color Paste together with porcelain plaster:
Provided the porcelain gypsum is kept in closed containers and stored in a cool, dry and frost-free location, the shelf life is at least 1 year.
As far as is known, the gypsum is harmless to humans and the environment. For additional information, please see the safety datasheet.
