Why do bubbles form when adding the curing agent?

This is a normal physical phenomenon where bubbles are produced during mixing; vacuum exhaust treatment is required.

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.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate, providing explicit evidence of a certified quality-management system. No other certifications are stated in the provided information.

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. Different molds result in varying viscosity, hardness, and density to meet client requests.

Q:Do you offer free samples?

Yes, we can provide samples for testing.

Q:How do you control quality?

We have a professional QC team that ensures 100% inspection of goods before shipment.

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 bubbles.

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

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