Extra hard with a Shore-Hardness of 32, 2 bottles with each 1 kg. The extra hard silicone unit is thought paticularly for large forms to prevent them from sinking in.
Specially suited for making complex forms, even with major undercuts. Due to very low viscosity air locks are hardly possible. The form can be filled with all popular casting compounds. The mixing ratio of 1:1 allows an easy mixing of the compound. Depending on the size of the form, the silicone form has hardened and can be filled within 30 - 60 min.
