AI-Powered supplier vetting

SummaryZibo Chico International Co., Ltd. is identified as a China-based trading company established in 2015, with three employees and an address in Zibo, Shandong. Its profile covers glass and building-material products, including pads, sealants, spacer bars, machinery, and desiccants. The submitted information also describes a manufacturing site in Zhengzhou with more than 10 production lines, 50 quality-control staff, and stated output capacities, although these manufacturing details are not clearly reconciled with the company’s trading-company classification and small employee count. No supplier management-system certifications are reported. The company claims broad export coverage, 90% export sales, overseas agents or distributors, and order fulfillment within 15 working days in both peak and off-peak periods. R&D resources appear limited, with one year of R&D-engineer experience. Trade records show one transaction associated with Ukraine and one with Colombia in 2025; these records provide limited evidence...

Supplier typeThe supplier is explicitly classified as a Trading Company and is registered as a Limited Company in China. Its stated business identity is therefore primarily commercial/intermediary rather than directly identified as a manufacturer.

CertificationsSupplier management-system certification is explicitly reported as NIL. Although the company states that selected brands have certified quality and that certain sealants are approved by IFT Rosenheim, this does not establish that the supplier itself holds management-system certifications.

After-Sales capabilityThe supplier describes consultancy, transportation, and local service support, and states that it works through overseas agents or distributors in multiple countries. These statements indicate an available support network, but no specific warranty, repair, complaint-handling, or service-level details are provided.

Production capacityThe profile states more than 10 production lines, 50 quality-control staff, a 50.0 m² manufacturing plant, and output capacities for sponge, silicone sealant, and cork pads, with fulfillment within 15 working days in both peak and off-peak seasons. However, the manufacturing information is not clearly consistent with the stated trading-company classification and three total employees, so capability is evidenced but should be verified.

Product Q&A

Q:What is the recommended mixing ratio for components A and B?

The mass ratio for Component A to Component B is 100:(6~12). The recommended best mixing ratio is 100:10. Adjusting the amount of Component B can alter the curing speed.

Q:Is this sealant suitable for hidden frame curtain walls?

No. Insulating glass prepared with MF840L cannot be used for hidden frame or semi-hidden frame installation applications (curtain walls). It is specially designed for exposed frame curtain walls.

Q:What are the storage conditions and shelf life?

Store in a cool, dry, and ventilated place. The shelf life is 12 months. Avoid exposure to direct sunlight.

Q:What substrates does this sealant adhere to?

It has excellent adhesion to glass (especially Low-E coated glass after film removal), aluminum alloy, stainless steel, coated, enamelled, and reflective glasses, as well as polyester paint coated aluminum.

Q:What is the minimum thickness required for gas-filled insulating glass?

For gas-filled insulating glass, the minimum thickness of the sealant is 5.0mm. Actual application should be based on the size and weight of the hollow glass unit.
