For General-use: HS-600
HS-600

The HS series features high water absorbency despite its low water-mixing amount and offers superior removal from new molds and improved forming efficiency. This plaster offers many advantages, such as shorter drying times due to quick diffusion of moisture within the mold.

Areas of use
General lathes and more

Packaging
25kg

For General-use: HS-650 (High grade equivalent)
HS-650

The HS series features high water absorbency despite its low water-mixing amount and offers superior removal from new molds and improved forming efficiency. This plaster offers many advantages, such as shorter drying times due to quick diffusion of moisture within the mold.

Areas of use
General lathes, pressure casting, and more

Packaging

For Wet Presses and Special Casting: C-100P
C-100P

This plaster is ideal for pressure-forming using tile and special ceramic presses.

Areas of use
Simple presses, wet presses, high-pressure casting, and more

Packaging

For Special Casting: C-100
C-100

>Clogging and moisture precipitation of fine particulates in plaster molds during casting can be prevented through air injection and washing. While the plaster mold is drying, air is injected and water is poured inside it, enabling the regulation of moisture levels (10–15%) ideal for quick casting. Because of this, cast drying using a heat source is unnecessary.

Areas of use
Special casting and more
