Why does adding curing agent create many bubbles?

This is a normal physical phenomenon. The liquid produces a large number of bubbles during mixing, so it must pass through vacuum exhaust bubble treatment.

Product Q&A

Q:What silicone products do you make?

We produce liquid silicone, silicone rubber, and silicone oil. Due to different silicone molds, our silicone has different viscosity, hardness, and density to meet client requests.

Q:Do you offer free samples?

Yes, we can provide samples for testing.

Q:How is quality controlled in your factory?

We have a professional QC team to control quality during production. Goods are 100% inspected before shipment.

Q:How to remove bubbles during mold making?

After mixing liquid silicone with curing agent, put the material into a vacuum machine to remove the bubbles.

Q:How to get a good silicone mold for longer use?

Choose the right liquid silicone according to your products. Do not use silicone oil in mold making as it makes the mold too soft. Wait 2 hours after the mold is finished to ensure full curing.
