Why does adding curing agent create many bubbles?

This is a normal physical phenomenon where the liquid produces many bubbles during mixing. It must pass through vacuum exhaust bubble treatment.

Product Q&A

Q:What silicone products do you make?

We produce rtv-2 silicone rubber, and silicone oil. Our silicone varies in viscosity, hardness, and density to meet specific client requests for different molds.

Q:Do you offer free samples?

Yes, we can provide samples for testing purposes.

Q:How do you control quality in your factory?

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

Q:How to remove bubbles during mold making?

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

Q:How to get a long-lasting silicone mold?

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