8. All kinds of certificates, such as MSDS,RoHS etc.
9. OEM service: various size of packages and customized labels
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.
