RTV2 Silicone Rubber for Polyester Resins is wonderful to make molds either with simple or intricate patterns, such as resin craft, artificial jewelry, resin arts, resin vase, resin flower ports
etc. With good resistance to heat, deformation, acid & alkali and expansion, finished
silicone molds serve very good performance in reproduction process with every fine
detail on designing models.
And the relative silicone material such as Polyurethane rubber (PU), Fiberglass, molding clay, thixotropic agent, silicone resin etc. With excellent profession in technology solutions and beautiful honest in after service. What we can provide is not only products but the real ability for how to help you getting the win-win market and active technicality support.
Appearance:
Part A: Silicone Rubber is an white liquid
Part B: Catalyst is an non-toxic and odorless liquid in transparent color.
ATT: we can provide catalyst of Fast, Medium,Slow for hot ,cold, warm season.

1. Do you offer free sample to client?
--Yes, we can provide the sample for test.
2. 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.
3. How to get good silicone mould to use longer time?
--The best way is:
#a, Please choose the right liquid silicone according to your products.
#b, Don’t use any silicone oil in mold making, because it can make the silicone mould become too soft to use.
#c, Silicone mould can be used longer after the whole silicone mould fully cured, so it’s better to wait 2 hours after mould finished.
4. 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.
