Why does adding curing agent create many bubbles?

This is a normal physical phenomenon where the liquid produces bubbles during mixing; it must pass through vacuum exhaust 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.

After-Sales capabilityThe supplier states that three doctoral senior researchers and 12 professional engineers support quality improvement, product development, innovation, and after-sales service. It also explicitly claims to provide technical solutions, after-sales service, and ongoing technical support, although no service-performance metrics or response-time data are provided.

R&D capabilityThe supplier explicitly reports top technology in condensation and addition-cured silicone in China and identifies doctoral researchers and professional engineers supporting new-product development and innovation. Its stated range of related silicone materials further supports technical breadth, though no independently verified innovation results are provided.

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 liquid silicone, silicone rubber, and silicone oil. Our silicone varies in viscosity, hardness, and density to meet specific client requests.

Q:Do you offer free samples?

Yes, we provide free samples for testing, but the customer must bear the international shipping cost.

Q:How is quality controlled in your factory?

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

Q:How do I remove bubbles during mold making?

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

Q:How can I get a silicone mold to last longer?

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