7. FAQ
What is the difference between fireproof neutral silicone sealant and ordinary silicone sealant?
Ordinary silicone sealant mainly focuses on sealing and bonding properties, and is used for general building sealing, waterproof and so on. In addition to sealing and bonding functions, the fireproof neutral silicone sealant also has fireproof properties. In the event of a fire, it is able to stop the spread of flames and smoke, and buy time for evacuation and fire rescue in the building.
What is the fire prevention principle of fireproof neutral silicone sealant?
Fireproof neutral silicone sealant will form a carbonized layer when heated. This carbonized layer has low thermal conductivity and can block the heat transfer of the flame, while preventing air from entering the combustion area, thus inhibiting the combustion reaction. And it can also prevent the spread of smoke to a certain extent and reduce the harm of smoke in fires.
How weather resistant is it?
Fireproof neutral silicone sealant has good weather resistance. It can maintain stable performance under different climatic conditions, such as high temperature, low temperature, wet, dry and other environments. Generally, it can withstand the temperature range of -40 ° C to 150 ° C, without cracking, deformation or loss of sealing performance due to temperature changes, and it can resist ultraviolet radiation and is not easy to age.
Is it environmentally friendly?
High-quality fireproof neutral silicone sealants are usually environmentally friendly. It will follow the relevant environmental standards in the production process to minimize the use of harmful substances. Generally speaking, it will not release a large amount of volatile organic compounds (VOC) after curing, which has a small impact on indoor air quality and meets environmental protection requirements, such as interior decoration.
What are the color options?
Common colors are black, white, gray and so on. These colors can meet the needs of different architectural decoration and sealing parts, such as white fireproof neutral silicone sealant can be used in the sealing of white walls or aluminum alloy window frames to achieve the dual effect of beauty and sealing.
How long does the sealant cure?
The curing time is affected by many factors, such as ambient temperature, humidity and the thickness of the sealant. Under normal circumstances, at room temperature (23 ° C, 50% relative humidity), the surface curing time is about 1-3 hours, and full curing may take 24-72 hours. The higher the temperature and the appropriate humidity, the faster the curing speed will be. Conversely, low temperature, high or low humidity may delay the curing process.
Which building materials are suitable for sealing?
It is suitable for sealing a variety of building materials, including but not limited to metal (such as steel, aluminum), glass, ceramics, stone (such as marble, granite), concrete, etc. For example, it can be used in the sealing of glass curtain wall and aluminum alloy frame, the gap sealing of stone curtain wall and the sealing of fire dividing joints in concrete structure.
Can it be used for interior decoration?
Can be used for interior decoration. In some parts with fire protection requirements, such as the gap seal between the indoor fire door and the wall, the sealing of the ventilation pipe through the firewall, etc., the fire neutral silicone sealant can provide fire protection function while ensuring the sealing effect, and because of its environmental protection, it will not cause greater pollution to the indoor environment.
