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 necessary.

What are the available mixing ratios?

Standard ratios include 100:3, 100:2, and 100:5, depending on the specific silicone series and application requirements.

Product Q&A

Q:What types of silicone products do you manufacture?

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

Q:Do you offer free samples for testing?

Yes, we can provide free samples for testing to help you evaluate the product quality.

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 material into a vacuum machine to remove the bubbles.

Q:How can I make silicone molds last longer?

Choose the right liquid silicone for your product, avoid using silicone oil (which makes molds too soft), and wait 2 hours after finishing the mold for full curing.
