Audited Supplier rtv2 silicone Platinum cured molding rubber is general called two-component room temperature vulcanization silicone rubber with excellent fluidity and good operational performance. Add Part A and Part B the same weight at room temperature, the silicone rubber is still operational within 20 to 40 minutes, and in 3-5 hours, an elastic silicon mold will be obtained.

1.Enclose the product (the original model) with four plastic plates or wooden plates
2.Clean your products and brush a layer of release agent (detergent or soap water) on your product.
3.Stir part A 100g and part B 100g with 1:1 mixing ratio evenly. And get the mixture for vacuum-pumping. (If there is no vacuum machine, you can just pour the mixture slowly from the corner so that less bubbles caused)
4.Pour the mixture with correct mixing ratio into the model frame. After about 2-4 hours, when the silicone cured, get out the original model, and there you get a finished addition cured silicone mold.

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.
If you don't have vacuum machine, just tell us, then we will solve it for you.
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.
