## Features

- ✔️R PRO FAST: Rapid prototyping 1:1 silicone rubber (the workability time is 5 minutes while the hardening time is 30 minutes) which creates rigid molds (35 shore) that last a long time and are excellent for casting wax, plaster, resins, cement and other materials.
- ✔️HIGH PERFORMANCE: It faithfully copies even the smallest details allowing you to make 20% more castings than other silicone rubbers.
- ✔️HARDNESS: The catalysed rubber allows you to make very rigid molds (hardness 35 ShoreA) and very "elastic" with a high resistance to tearing.
- ✔️MOLD PERFORMANCE: The physical life of the mold depends on how it is used (cast materials, frequency, etc.). Casting abrasive materials such as concrete can quickly erode mold detail, while casting non-abrasive materials (wax) does not affect mold detail.
- ✔️NOTE: Sulfur-based modeling clay is NOT compatible and may inhibit the catalysis of R PRO rubbers.

Beaucoup trop difficile à démouler . Reste trop rigide pour une pièce en 3D . De ce fait la pièce casse au demoulage. Grande déception vu le prix
