Why does adding curing agent cause many bubbles?

This is a normal physical phenomenon where mixing produces bubbles; the material must undergo vacuum exhaust treatment to remove them.

AI-Powered supplier vetting

SummaryGuangzhou OTT New Materials Co., Ltd. is a China-based limited company established in 2014, operating in silicone and related chemical materials. It reports five production lines, a 1,700 m² manufacturing plant, broad product coverage, exports representing 90% of total sales, and stated peak- and off-peak-season fulfillment within 15 working days. The supplier holds ISO 9001:2015 certification and describes technical support, after-sales service, and silicone-material innovation capabilities. However, the available information indicates a relatively small organization of 17 employees, fewer than five quality-control staff, and limited documented customer-trade evidence. Financial strength, customization performance, and the depth of customer cases cannot be conclusively assessed from the provided data.

Product Q&A

Q:What silicone products do you make?

We produce liquid silicone, silicone rubber, and silicone oil. Viscosity, hardness, and density vary based on the specific mold type to meet client requests.

Q:Do you offer free samples?

Yes, we can provide samples for testing purposes.

Q:How is quality controlled in your factory?

We have a professional QC team that inspects goods 100% before shipment to ensure quality during production.

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

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