Description of RTV2 Silicone for Plaster Ornaments Moulding
RTV2 Silicone for Plaster Ornaments is generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.

Silicone Mold-making Procedures:
1. Clean and prepare specimen (apply consolidant, sealant, or release agent if necessary).
2. Build retaining wall around specimen.
3. Stir silicone base to loosen any settled material.
4. Decant desired amount of silicone into mixing container.
5. Mix in appropriate amount of catalyst.
6. Apply to specimen.
7. If reinforced mold is desired, gently press in gauze after pouring fist layer.
8. When cured, gently remove mold from specimen.
9. If needed, create rigid backing or jacket over mold with plastic,
urethane foam, or plaster.
10. Remove backing material and mold. Store mold inside rigid backing.
