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.

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.

Supplier typeThe supplier is identified as Guangzhou OTT New Materials Co., Ltd., a China-based limited company operating in chemicals and silicone materials. Its listed products include architectural-restoration silicone and mold-making silicone, while its broader product keywords cover multiple liquid, RTV, cured, and specialty silicone products.

Production capacityThe supplier reports five production lines, a 1,700 m² manufacturing plant, and order fulfillment within 15 working days in both peak and off-peak seasons. Its product scope is broad and export sales are stated to represent 90% of total sales, but the small total workforce of 17 employees and fewer than five quality-control staff indicate that operational scale should be verified for large-volume requirements.

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.
