Anpak TU is a hemihydrate plaster (CaSO4x1/2 H2O) produced from naturally occurring gypsum mineral. It is off-white in colour.
This product is used in the ceramics tableware industry to produce working moulds for the jiggering and jollying when good mould life and excellent reporduction of details are requiered.
Design for Jiggering
Very fine reproduction of details
Excellent workability for efficient mould making

| Plaster to Water Ratio | |
|---|---|
| Plaster to Water Ratio (by weight) | 1.60:1 |
| Water to plaster ratio ( by weight) | 62.5% |
The recommended plaster to water ratio is between 1.55:1 and 1.65:1, with a mixing time of approx. 2 to 4 minutes, depending on batch size and plaster shop process. Water and Plaster must be measured carefully to ensure constant performances. The precise consistency to use will need to be adjusted to suit the individual application. Changes to plaster to water ratio will influence product performance particularly setting time, strength and permeability.
