Meets the requirements of ISO 6873-3.

Certificate of Approval No. IL-5629/MS.

Advantages:

• obtaining high-durability models;
• minimum, uniform coefficient of expansion;
• constant level of quality.

Physical properties :

• hardening time: approx. 10 min;
• compressive strength after 1 h: more than 20 N / mm2;
• hardness after 24 h over 80 N/mm2;
• Linear expansion after 2 hours: less than 0.14%.

Mixing proportions and method of use:

• plaster 100 g : 30 ml;
• water : gypsum 0.3 ml / g;
• operating temperature approx. 23 °C;

• wait 20 seconds until the water is absorbed by the plaster;
• mechanical mixing: 30 sec;
• hand mixing: 60 sec;
• during this time, the plaster reaches the optimal consistency for pouring into model molds on a shaker;
• shaking time: approx. 6 min;
• After this time, stop shaking so as not to disturb the crystallization process.
