Fire rating and flame retardant properties of A Gaoseil A119 fireproof adhesive
Gaoseil A119 fireproof adhesive has good fire resistance and flame retardancy. This product can achieve a fire resistance level of A3 and effectively block fire for up to 3 hours at high temperatures exceeding 1000 ℃. At the same time, the flame retardant level also reaches FV-0 level, which does not support combustion when exposed to open flames, extinguishes automatically after leaving the fire, and does not release thick smoke.

Below is a table format to help you quickly understand Gaoseil A119 fireproof adhesive:

Fire retardant sealing for curtain wall engineering

Used for flame retardant sealing of various layers of building curtain walls to prevent the spread of fire through the curtain wall cavities

Fire sealing in public places

Suitable for fire prevention treatment in densely populated public places such as hotels, inns, theaters, shopping malls, hospitals, schools, etc

Other industrial uses

Can be used for some industrial facilities that require fireproof sealing

Attention to use: Gao Lide A119 fireproof adhesive cannot be used as a structural bonding material.
Before construction, it is necessary to conduct compatibility and adhesion tests on the actual substrate used, and only after confirming that it is qualified can large-scale construction be carried out.
The surface temperature of the construction substrate should generally not be lower than 4 ℃ or exceed 40 ℃ to ensure good ventilation in the construction site.
The product should be stored in a cool and dry place, and used within its shelf life.


B、 How to choose building flame retardant and fireproof adhesive?
1. Confirm the fire retardant rating and clarify the fire resistance limit requirements for fire sealant in engineering design fire related specifications.
2. Attention should be paid to environmental protection and safety. Modern buildings emphasize material environmental protection and should choose Gaoseil A119 fireproof adhesive that meets the standards. It is crucial to ensure the safety of personnel evacuation in the event of a fire.
3. Assess the bonding performance and substrate used to ensure good adhesion between the fireproof adhesive and the actual building materials used (such as concrete, metal, glass, stone, etc.).
4. The weather resistance and durability of the product, especially when it is used for external joints such as curtain walls, doors and windows, etc., the fireproof sealant needs to withstand a long-term temperature difference test. Therefore, excellent ultraviolet resistance, ozone resistance, high and low temperature resistance and anti-aging performance are the key to ensure the long-term fireproof effect of the sealed box.
