Why do bubbles form after adding the curing agent?

This is a normal physical phenomenon. Liquid produces many bubbles during mixing, so vacuum exhaust bubble treatment is required.

Product Q&A

Q:What types of silicone products do you manufacture?

We produce liquid silicone, silicone rubber, and silicone oil. We adjust viscosity, hardness, and density to meet specific client requirements.

Q:Do you offer free samples to clients?

Yes, we can provide free 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 can I remove bubbles during mold making?

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

Q:How can I make my silicone mold last longer?

Choose the right liquid silicone for your product, avoid using silicone oil (which makes molds too soft), and allow the mold to fully cure for at least 2 hours after finishing.
