Does every application achieve the same fire rating?

No. Fire resistance depends on the tested joint system, substrate, joint dimensions, backing material, sealant depth, and installation method. Please confirm the applicable test report before specifying the product.

What packaging options are available?

Standard packaging options include 300 mL cartridges and 500 mL sausages. The standard packing quantity is 12 tubes per carton.

What colors are available?

Standard colors include black and white. Other colors may be available for qualified project quantities.

What is the shelf life?

The shelf life is 12 months when the product remains unopened and is stored according to the recommended storage conditions.

How should the joint surface be prepared?

The surface should be clean, dry, and free from dust, oil, grease, rust, and loose material. Primer or additional surface treatment may be required for certain substrates.

Do you support OEM and customized packaging?

Yes. OEM, ODM, private labeling, customized packaging, and project-specific production are available subject to order requirements.

What information is required for a quotation?

Please provide the required packaging size, color, quantity, application substrate, joint dimensions, test requirements, destination country, and any OEM or packaging requirements.

AI-Powered supplier vetting

SummaryThe supplier operates in rail transit, high-speed rail equipment and accessories, new energy technologies, technical glass, fireproof sealing materials, and related special equipment. It reports extensive customization capability, OEM service for recognized brands, standardized finished-product inspection, and multiple quality, environmental, occupational-health, fire-protection, and EU certifications. Its company description states that it has served nearly a thousand major enterprises and achieved an average annual order delivery rate above 98%. However, the provided information indicates no valid manufacturing-capacity contract with an affiliated subcontractor, no inventory, overseas warehouse, overseas showroom, overseas agent or branch, or offline trade-show participation. Financial credibility cannot be assessed because the supplied financial fields contain zero values and no reliable supporting explanation.

Supplier typeThe supplier is positioned as a seller and developer of rail transit and high-speed rail equipment, rail transit green composite materials, new energy prime movers and technologies, technical glass, fireproof sealing materials, and special equipment. The scope indicates an industrial equipment and component supplier with research and development activities, rather than a general trading-only business.

CertificationsThe supplier reports ISO9001:2015, ISO14001, ISO45001, EU CE certification, 17 fire-protection product certificates issued by the Ministry of Emergency Management Fire Assessment Center, and more than 20 EU fire-resistant material certificates. This is explicit evidence of broad quality, environmental, occupational-health, fire-product, and EU compliance certification.

R&D capabilityThe supplier describes its products as innovative and offers research and development activities in emerging energy technologies and nuclear-power equipment assembly and engineering technology. It also supports customization and OEM services, but reports no available SDK; the evidence supports product and engineering innovation activity without establishing a complete software-development capability.

Customization capabilityThe supplier explicitly offers flexible customization, minor customization, full customization, customization from customer designs, and customization from samples. Its description also states that products can be customized according to actual needs, providing direct evidence of broad customization capability.

Client casesThe supplier states that it has long served nearly a thousand major enterprises and reports OEM service for recognized brands. It also cites extensive fire-protection and EU fire-resistant material certifications, but no specific customer names, project descriptions, or independently verifiable case details are provided.

Product Q&A

Q:What is FQ-N?

FQ-N is a ready-to-use, one-component fire-resistant silicone sealant designed for sealing construction joints and gaps where flexibility, smoke sealing, and fire-resistant performance may be required.

Q:Does the sealant need to be mixed before application?

No. It is a one-component product and can be applied directly from the cartridge or sausage without on-site mixing.

Q:What substrates can it bond to?

It is suitable for compatible substrates such as glass, aluminum, stainless steel, and other common construction materials. An adhesion test is recommended before large-scale application.

Q:Is FQ-N suitable for vertical joints?

Yes. Its non-sag paste consistency makes it suitable for both vertical and horizontal joints when applied correctly.

Q:What is the skin formation time?

The typical skin formation time is approximately 15 minutes. Actual time may vary depending on temperature, humidity, joint dimensions, and site conditions.
