Why do bubbles form after adding the curing agent?

This is a normal physical phenomenon where mixing introduces air. The mixture must undergo vacuum exhaust treatment to remove these bubbles.

What is the typical shelf life of the silicone?

The silicone has a remarkable shelf life of 18 months when stored in a cool, dry environment with an unopened package.

What are the available packaging and shipping options?

Packaging ranges from 1KG to 1000KG drums. We offer flexible shipping by air or sea with swift delivery within 4-6 days after payment confirmation.

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 types of silicone products do you manufacture?

We produce liquid silicone, silicone rubber, and silicone oil. Viscosity, hardness, and density vary based on the specific mold requirements.

Q:Do you provide free samples for testing?

Yes, we can provide free samples for clients to test the product quality before placing an order.

Q:How do you ensure quality control during production?

We have a professional QC team that controls quality throughout 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 in a vacuum machine to remove the bubbles effectively.

Q:How can I extend the lifespan of my silicone mold?

Choose the correct silicone for your product, avoid using silicone oil (which softens the mold), and allow the mold to fully cure for at least 2 hours after finishing.
