DESCRIPATION
Silicone rubber is a two-component material, consisting of Part A base and Part B MCSIL-CA30, cures at room temperature by a condensation reaction. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.
APPLICATIONS
MC RTV-2 mold making silicone rubber are suited for reproduction of
casting stone, cement molding, concrete stones, artificial stones,
art stone, fake stone, artificial rock, cultrured stone, etc.
PRODUCT FEATURES
1. Good flow ability 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

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: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle
Certificates
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 10 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.
