Why does adding curing agent create many bubbles?

This is a normal physical phenomenon where liquid produces bubbles during mixing. It must undergo vacuum exhaust bubble treatment.

Product Q&A

Q:What silicone products do you manufacture?

We produce liquid silicone, silicone rubber, and silicone oil. Different molds require specific viscosity, hardness, and density to meet client requests.

Q:Do you offer free samples to clients?

Yes, we can provide samples for testing purposes.

Q:How is quality controlled in your factory?

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

Q:How do I remove bubbles during mold making?

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

Q:How can I get a silicone mold that lasts longer?

Choose the right liquid silicone for your product, avoid using silicone oil as it softens the mold, and wait 2 hours after finishing the mold for full curing.
