Introduction of Concrete Stone Mold Making RTV Silicone Rubber
RTV-2 is a two-component Room-Temperature-Vulcanizing (RTV-2) silicone rubber. Depending on its curing mechanism, two types of RTV-2 are available: "condensation" cure type and "addition" cure type. Generally, RTV-2 Silicone Rubber is a kind of two-component material. The RTV-2 silicone rubber is made up of Part A base silicone and Part B curing agent. The Part A base silicone and Part B CA curing agent can cure at room temperature by a condensation reaction, after full cure, it become a cured silicone mold. The silicone mold can be cast the following materials for reproduction: Plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...
Characteristics of Concrete Stone Mold Making RTV Silicone Rubber
1. Good flow ability and long working time
2. Medium hardness
3. High tear and tensile strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Low linear shrinkage
Applications of Concrete Stone Mold Making RTV Silicone Rubber
RTV-2 silicone rubber for mold making can be used in the filed of reproducing cement molds, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. etc.
RTV-2 silicone rubber can be applied in many objects mold making, since the RTV-2 silicone has good flow ability and medium hardness, and the silicone can cure at room temperature, thus it's a good material for duplication.
RTV-2 Silicone Rubber can be used for artificial stone mold making. For example MCSIL-2066 and MCSIL-2088 silicone.
RTV-2 silicone rubber can be applied in candle and soap mold making, such as MCSIL-215 and MCSIL-218 silicone.
RTV-2 silicone rubber can be used for plaster mold making, such as MCSIL-2025, MCSIL-H25 and MCSIL-2030 silicone.
RTV-2 silicone rubber can be applied in the field of shoe sole moldmaking, for example, MCSIL-S10 and MCSIL-S15 silicone.
RTV-2 silicone rubber can be used for prototyping and electronic potting.
MCSIL-2066&2088 silicone rubber is especially suited for reproduction of middle size cement molds, concrete stones, and artificial stones. etc...
Packing of Concrete Stone Mold Making RTV Silicone Rubber
Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 0.25kg/bottle, 1kg/bottle and 10kg/bottle
Storage of Concrete Stone Mold Making RTV Silicone Rubber
When the RTV-2 silicone rubber is stored at or below 30 C (85F) in the original unopened containers, Silicone Base and CA30 Curing agent have a usable life of 12 months from the date of production.
Note of Concrete Stone Mold Making RTV Silicone Rubber
RTV2 silicone rubber is an industrial product and must not be used in food molding, dental human skin molding applications.
