This is one of the hardest and strongest gypsum cements. It is used for producing high-quality novelty and statuary castings requiring extremely hard surfaces. Not suitable for hollow products. Has a high water absorption resistance. Works well in plaster and most flexible moulding compounds.

Slightly higher setting expansion than Hydrocal, but is ideal in case moulds, press and stretch dies.

• Dry compressive strength 10,000 psi. 
• Setting Expansion: 0.24%

Suited for the castings of hands and feet in alginate, or solid and statuary casts.
