ShinEtsu Similar 30 Shore A White Tin Cure RTV2 Silicone Mold
Rubber Sculpture / Statue Molds Making
Product Description
Silicone liquid rubber is called Tin cure silicone rubber which is
also called condensation-cure silicone mold rubber, these are
high-tear silicone mold rubbers that are known as the “work horse”
of the industry because of their performance and economy. Tin cured
silicone molds are used for casting wax, cement, gypsum, polymer
modified gypsum, resins, etc.
Various Applications of silicone liquid rubber
A: Cultural relic duplication, architectural decoration, statues
B: Resin crafts
C: Lighting ornaments, candles
D: Plaster, Gypsum,Cement,Concrete decorations
F: Model design, product exploitation, etc.

Typical Properties of RTV-2 silicone liquid rubber
Operation Instructions of Silicone Liquid Rubber
Correct mixing ratio
Component A is silicone rubber, and component B is curing agent or
vulcanizing agent. Usually the mixing ratio will be 2-3%, e.g. to
100g silicone rubber should be added 2g catalyst and then mix them
thoroughly. (Note: the weight of the silicone and catalyst should
be weighed correctly).
Pouring the mixture and curing
Pour the misxed Part A base silicone and CA-30 curing agent as soon
as possible onto the original,avoiding air entrapment.The catalyzed
material will cure to a flexible rubber within 6 hours(or faster by
different mixing ratio or room temperature),we advice you de-mold
after 24 hours ,it is will improve the replicate times of silicone
mold.
Package of RTV-2 Silicone Liquid Rubber
Part A base silicone: 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle
Storage & Shelf life
When the silicone rubber is stored at or below 25℃ (77℉) with the
original unopened containers, Silicone Base and Curing agent have a
usable life of 12 months from the date of production. After 12
months stock, please use the Stir machine to mix the Part A
silicone for some minutes, then the silicone can be used again, no
influence for other performance.
