In modern buildings, a sudden fire may devour everything in an instant. How to buy precious escape time for life at a critical moment? Fireproof sealant-this "invisible guard" that protects building safety is providing a safety umbrella for millions of buildings around the world with its excellent fireproof performance.

What are the performance advantages of fireproof sealant?

1. 3-hour fireproofing time

Adopting advanced expansion formula, it can still maintain the complete structure for more than 3 hours at a high temperature of 1000℃. When the flame spreads, the glue layer expands rapidly to form a dense carbonized layer, which effectively blocks heat transfer and buys critical time for rescue.

2. Full-scene protection capability

Applicable to 12 major fields such as building curtain walls, power pipelines, and rail transit. Whether it is concrete walls, metal pipelines or glass curtain walls, seamless sealing can be achieved to form a complete fire barrier.

3. Environmental protection and safety dual certification

Passed China CCCF mandatory certification, does not contain asbestos and other harmful substances. The neutral curing formula is non-corrosive to the substrate, and there is no irritating odor after construction, ensuring the health of personnel.

As an industry benchmark company, our FST series fireproof sealants can replace international brands such as 3M and HILTI, etc.

- FST8076 expansion sealant: The expansion rate in case of fire is 800%, and it is used with metal fireproof board, which is a good partner in fireproof materials;

- FST8075 elastic sealant: Displacement capacity ±25%, excellent seismic performance;

- FST8074 silicone sealant: Excellent weather resistance, suitable for outdoor curtain walls.

So how to choose fireproof sealant? It is recommended to follow the "six-dimensional evaluation method":

1. Fire rating: select 1-3 hours fire resistance limit according to GB23864 requirements

2. Environmental adaptation: high temperature/high humidity/chemical corrosion environment requires special customization

3. Substrate matching: metal/concrete/wood requires corresponding bonding formula

4. Displacement compensation: dynamic joints are recommended to choose products with displacement capabilities

5. Convenient construction: single-component design can be directly extruded for construction

6. Long-term protection: give priority to products certified by CCCF
