Tin Cure High Strength Brush On Silicone Liquid Rubber for Making
Statue Sculpture Molds
Product Description
MC Silicone Rubber RTV-2 series mold rubbers are two-component,
condensation-cure, tin-catalyzed, very high tear strength, flexible
mold compounds. A tough, knotty tear strength making them
especially valuable to the mold making industry. RTV2 series mold
rubbers are recommended for evaluation as mold materials for
polyester, epoxy and polyurethane resins, as well as for waxes and
many other materials

Instruction of RTV-2 silicone liquid rubber:
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 pour molding is an easy way to make molds, it’s Slowly and
evenly perfuse the mixed silicon rubber into the square frame.
After the cross linking reaction.

Storage and Precautions of silicone liquid rubber:
RTV-2 silicone rubber for making art crafts, which is an
environmentally-friendly liquid silicone product, is not easy to
burn and can be stored and transported as non-hazardous goods. The
shelf life of the product is about one year from the date of
production. Inspection is required when exceeding the time limited.
It can continue to be used in case of neither thickening nor
deterioration.
Why RTV-2 Mold Making Silicone Rubber?
Economic Use
As the most stable polymer available, silicones offer superior
reliability, excellent service life and reduced production costs.
Versatile Application
