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.

Product Q&A

Q:What's silicone products you are making?

liquid silicone, silicone rubber, silicone oil; Due to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client.

Yes, we can provide the sample for test.

Q:How about the quality control in your factory?

Q: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.

Q: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.
