Introduction of high quality Silicone Rubber for Sculpture Mold
Making
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...

Applications of high quality Silicone Rubber for Sculpture Mold
Making
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
moldmaking.For example MCSIL-2066 and MCSIL-2088 silicone.
RTV-2 silicone rubber can be appliied in candle and soap
moldmaking, such as MCSIL-215 and MCSIL-218 silicone.
RTV-2 silicone rubber can be used for plaster moldmaking, 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-S20 and MCSIL-S25 silicone.
RTV-2 silicone rubber can be used for prototyping and electronic
potting.
Procedures of high quality Silicone Rubber for Sculpture Mold
Making
1. Make sure the surface of the original is clean and free of loose
material.
2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a
clean container.
3. Stir Part A base silicone before use thoroughly, as filler
separation may occur upon prolonged storage.
4. Mix Part A and Part B evenly until the CA30 completely dispersed
in the base.
5. Pour the mixed Part A base silicone and CA-30 curing agent as
soon as possible onto the original
6. De-mold after 24 hours, it is will improve the replicate times
of silicone mold.
Note: It is strongly recommended that entrapped air be removed in a
vacuum chamber, allowing the mix to completely expand and then
collapse. After a further 1-2 mins under vacuum, the mix should be
inspected and can be used if free of air bubbles. A volume increase
of 3-5 times will occur on vacuum de-airing the mixture. So a
suitably large container should be chosen.
