Creartec Silcolan NV-RTV Mould Making Silicone Rubber

• Thin-flowing silicone rubber with excellent durability  for casting or spreading.
• For the production of molds (single or multi-piece) and the copying of detailed objects.
• Once hardened, you can cast: polyurethane resins, polyester, clay, wax, soap, plaster, etc.

Instructions

1. Prepare the original object you want to copy by protecting it with non-stick coating.
2. Add the hardener (small bottle) to the silicone rubber in a ratio of 1.5 to 2.5% (40 drops of hardener equals approximately 1gr).
3. Circulate the original object (after placing it in a frame code 1900064) or coat it with the rubber.
4. The rubber hardens in approximately 2-4 hours.
5. Carefully separate the original object from the rubber.
6. You can now cast the material you want inside (e.g. polyurethane resin, polyester, soap, wax, plaster, etc.) having coated the silicone mold with the appropriate anti-stick agent.
