Description of RTV-2 Silicone Rubber Material for Stone Wall molds
making
RTV-2 silicone rubber is a two-component material, this kind of
silicone rubber consists of Part A base silicone and Part B CA30
curing agent, and Part A base silicone and Part B curing agent can
cure at room temperature by a condensation reaction. These
materials can be cast into the cured silicone molds: Plaster
polyurethane, PU, GRC, cement, resin, polyester, wax etc...
Features of RTV-2 Silicone Rubber Material for Stone Wall molds
making
1. Good flowability 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 RTV-2 Silicone Rubber Material for Stone Wall molds
making
RTV2066&RTV2088 silicone rubber is especially suited for
reproduction of middle size cement molds, concrete stones, and
artificial stones. etc...
Storage of RTV-2 Silicone Rubber for Stone Mold Making
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.

How to make the silicone mold?
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.
