A kind of room temperature vulcanized silicone rubber in condensation type. It's generally named as two part silicone rubber , Part A is a flowable liquid, part B is the curing agent or catalyst . It's mainly used for mold making .
Used for making molds of concrete stone,GRC, gypsum decoration , plaster ornaments, fiberglass products, polyester decoration, unsaturated resin crafts, polyresin crafts, polyurethane, bronze, wax, candle, and similar products .
This kind of silicone rubber is with moderate hardness in high tensile and tear strength ,which is suitable for middle or large size product with pattern by both pouring and brushing operation, especially popular for manufacturer of gypsum decoration and concrete molding .Additive is available for brushing operation . It's one of our best selling silicone !
Advantages
*An exceptional fluidity and good operability, easy to demold *Good tensile and tear strength *Outstanding bubble releasing *Non-deformation *Low shrinkage *Aging resistance ,high temperature resistance (200℃) *Envirnmentally, food-grade

Notes
The operation of Liquid silicone medical for realistic silicone film mask: is platinum cure silicones, so substances, such as water, impurity, organic tin catalyst, acid, alkaline and other organisms containing sulfur, phosphorus and nitrogen, will influence the vulcanization of the lifecasting silicone rubber. So, please do not mix with or touch those substances during your operation process.
-- According to different silicone molds, our silicone has different viscosity, and cause different hardness,
density to meet the requests from client.
2. Do you offer free sample to client?
--Yes, we can provide the sample for test.
3. How about the quality control in your factory?
--We have professional QC team.
--Each batch of silicone rubber must be tested by our safe quality examination system.
4. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles.
5. How to get good silicone mould to use longer time?
--The best way is:
1, Please choose the right liquid silicone according to your products.
2, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use.
3, Silicone mould can be used longer after the whole silicone mould fully cured, so it's better to wait 2 hours after mould finished.
6. Why silicone rubber add curing agent after mixing a lot of bubbles?
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
