## Features

- ✔️R PRO TECH 33: Mixing ratio 1:1 (both by volume and weight), heat resistant up to 350°C, cures at room temperature. Molds made with R PRO TECH 33 are long-lasting and excellent for casting resins, wax, plaster, cement, and other materials, widely used in the professional jewelry sector.
- ✔️HIGH PERFORMANCE: R PRO TECH 33 faithfully reproduces even the smallest details, allows up to 20% more castings compared to other silicones. Working time: 45 minutes – Curing time: 3 hours.
- ✔️HARDNESS: Once cured, this silicone produces medium-hardness molds (33 Shore A) with high tear resistance.
- ✔️MOLD PERFORMANCE: The physical lifespan of the mold depends on its use (casting materials, frequency, etc.). Casting abrasive materials like concrete can quickly wear down mold details, while non-abrasive materials (such as wax) preserve them.
- ✔️NOTE: Sulfur-based plasticine is NOT compatible and may inhibit the curing of R PRO silicones.
