RTV-2 silicone rubber for plaster statues :
Production mold casting wax, gypsum, concrete or resins (urethane,
polyester, etc. ). Applications include reproducing sculpture,
architectural restoration, making candle molds, casting pewter,
place couldnt pour rubber over the above etc. For make a mold by
brushing (or spraying) rubber onto the model. Rubber will hold a
vertical surface and will reproduce the finest detail brushed onto
the model in layers until a suitable thickness is built up.
RTV-2 silicone rubber for plaster statues is allowed to cure and a support shell is applied prior to
demold. The advantage of making a mold by brushing rubber onto the
model is that it minimizes the amount of rubber used, saving
Sprayable Rubber For making fast sprayed rubber molds that have the
best release properties for production casting of resins, plaster,
etc. It is a tin silicone rubber that self-thickens for making
concrete Spray able -on molds. Properly applied, Mixed 100A: 5B by
weight, rubber quickly develops thixotropy when mixed in air. Cured
with negligible shrinkage to a durable mold rubber good for
production casting resins, foams, concrete, plaster and other
materials. Application of a support shell is achieved by spraying
over the rubber mold after it has fully cured.
Silicone Putty: Mix & Apply By Hand Silicone putties are
two-component, tin-cure silicone putties that can be applied
"on-site"--directly to almost any model; Capturing the finest
detail and curing within minutes. Silicone Putty has been used to
make molds of valuable antiques and archeological models and can be
used to make fast molds of sculpture, prototypes, candles, picture
frames, coins, etc. Also can cast wax, gypsum and a variety of
resins into Putty molds.

free to contact us,we can produce silicone follow your request.
using instruction on RTV-2 silicone rubber for plaster statues molds for big size:
Component A is white flowing liquid and component B is the curing
agent. For example, take silicone rubber of 100g and add 2g curing
agent for mixing evenly (silicone rubber and curing agent must be
measured accurately). After the silicone rubber and the curing
agent are completely mixed, put the silicon into a vacuum machine
for deairing to remove the bubbles. After deaired, pouring the
liquid silicone rubber into the product to be duplicated or into
the mold frame. If you don't have vacuum machine, please add 1.2%
or 1.5% curing agent so that the bubbles can bubble itself. Since
the less curing agent you add, the slower the mould will curdle,
the bubbles will bubble out itself.
