Tin Cure Silicone Rubber for Making Relief Scuplture Molds
DESCRIPATION
MCSIL is suitable for a variety of art-related and industrial
applications including making molds for sculpture and prototype
reproduction, casting plaster, resins and wax.. When mixed with
2-3% curing agent, they can still be operated within 30-40 minutes,
but will be formed after 4-6 hours. With resistance to deformation,
high temperature, acid and alkali, and expansion.
PRODUCT FEATURES
1. Good flow ability and long working time
2. No oily
3. Excellent performance, fine details
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.
APPLICATIONS
RTV-2 silicones are specifically designed to replicate stones,
marble, wood, and other construction materials, producing
outstanding fidelity for every detail, including veins and surface
texture. The various grades of architectural molding silicones
enable builders to replicate accurately the look they desire while
providing long mold life and excellent resistance against casting
materials.
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.
