Description of silicone rtv2 for cement stone mould:
Silicone rtv2 for cement stone mould, rtv2 silicone rubbers are generally named as two-part room temperature cure silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.
Features of silicone rtv2 for cement stone mould:
High tear strength
Low linear shrinkage
Good flowability
High duplication times
Procedures how to make a RTV silicone mold:
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.
STORAGE of Silicone RTV2 for Cement Stone Mould:
When the silicone rubber is stored at or below 30 ° C (85 ° F) in the original unopened containers, RTV2 Silicone Base and CA30 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.
