Manufacturer of Manufacturer of RTV2 Liquid Silicon Rubber
RTV-2 silicone rubber is a two component material, and it consist
of Part A base silicone and Part B curing agent. When the two parts
mix together and pour or brush on a object, the silicone base and
curing agent can cure to be a silicone mold at room temperature;
And 24 hours later, the silicone mold can be released from the
object, and then the silicone mold can be poured into the following
material to copy: Plaster, polyurethane, PU, GRC, cement, resin,
polyester, wax etc...
Procedures of Manufacturer of RTV2 Liquid Silicon Rubber
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.
Extensive Applications of Manufacturer of RTV2 Liquid Silicon
Rubber
RTV-2 silicone rubber can be used in the duplication of cement
molds, concrete stones, artificial stones, plaster molding,
figures, art objects, decoration molding, GRC products, gypsum
products, resin products, PU molds. etc.
