Why do bubbles form after adding the curing agent?

This is a normal physical phenomenon. Liquid silicone produces many bubbles during mixing, so vacuum exhaust treatment is necessary to remove them.

Product Q&A

Q:What types of silicone products do you manufacture?

We produce liquid silicone, silicone rubber, and silicone oil. Our silicone viscosity, hardness, and density vary based on the specific mold requirements.

Q:Do you provide free samples for testing?

Yes, we can provide samples for clients to test the product quality and performance before placing an order.

Q:How do you ensure product quality?

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 mixture in a vacuum machine to remove bubbles effectively.

Q:How can I extend the lifespan of my silicone mold?

Choose the right silicone for your product, avoid using silicone oil which softens the mold, and allow the mold to fully cure for at least 2 hours after completion.
