Procedures of mold making by RTV-2 Silicone Rubber

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.

Package 

Part A base silicone: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle

 

Storage 

When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone Base and Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.

 

Note of RTV-2 Silicone Rubber For GRC Mold Making

MCSIL silicone rubber is an industrial product and must not be used in food molding, dental human skin molding application.
