Introduction of RTV-2 Silicone Rubber 25 Shore A
MC silicone RTV2025 is a low viscosity, medium hardness condensation cure silicone rubber. Idea for the pouring of flood moulds, formulated to give precise reproduction. Setting times can be adjusted to suit the size of each individual job by using between 2%-5% catalyst.
Applications and Features of RTV-2 Silicone Rubber 25 Shore A
MC silicone RTV2025 is suited for the detailed reproduction of figures, plaster casting, art objects and similar items. It retains outstanding release properties, high flowabilty, high tear resistance and high elasticity for easy removal of complex replica pieces. The components mix easily and because of the low viscosity can be used without processing in a vacuum chamber.
Procedures of mold making by 2 part Liquid RTV 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.
