APPLICATIONS
MC Silicone RTV2 series are suited for reproduction of cement
molding, concrete stones, artificial stones, plaster molding,
figures, art objects, decoration molding, GRC products, gypsum
products, resin products, PU molds, etc.
USING INSTRUCTION
1- Take 100g of part A and add 2g of part B and mix the silicone
rubber and curing agent evenly.
2- vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise,
it will cause , and no more further steps will be available
3- Pouring mold or block mold of silicone rubber
The pouring way is an easy way to make molds, it's slowly and
evenly pour into the mixed silicon rubber into the square frame.
After the cross linking reaction.
Package
Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle

Storage
When the silicone rubber is stored at or below 30 centi degree in
the original unopened containers, Silicone Base and Curing agent
have a usable life of 10 months from the date of production. After
12 months stockpiles use the Stir to mix the Part A silicone for
some minutes, then the silicone can be use again, no influence for
other performance.
