Concrete Stone Molding Silicone Liquid Rubber

Description of Concrete Stone molding silicone rubber:

Concrete Stone molding silicone rubber, 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 Concrete Stone molding silicone rubber:

High tear strength
Low linear shrinkage
Good flowability
High duplication times


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.
