Why does adding curing agent create many bubbles?

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

Product Q&A

Q:What silicone products are you making?

We produce liquid silicone, silicone rubber, and silicone oil. Our silicone varies in viscosity, hardness, and density to meet client requests for different molds.

Q:Do you offer free samples to clients?

Yes, we can provide samples for testing purposes.

Q:How is quality control handled in your factory?

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

Q:How to remove bubbles during mold making?

After mixing the liquid silicone with the 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 for your products, do not use silicone oil as it makes the mold too soft, and wait 2 hours after finishing the mold for full curing.
