Description of liquid rubber silicone for concrete stone molding

liquid rubber silicone for concrete stone molding , RTV-2 Silicone (room temperature vulcanization silicone) is a type of silicone rubber made from a two-component system (base plus curative; A+B) available in a hardness range of very soft to medium - usually from 15 Shore A to 40 Shore. RTV Silicones can be cured with either a platinum catalyst or a tin catalyst. Applications include making molds for reproducing.

Applications of liquid rubber silicone for concrete stone molding

liquid rubber silicone for concrete stone molding , RTV-2 Silicone will reproduce the finest detail and is suitable for a variety of industrial and art related applications including prototypes, furniture, sculpture and architectural elements. RTV-2 Silicone can also be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins (without using a release agent).

Features of liquid rubber silicone for concrete stone molding

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.
