In construction, the safety and environmental protection of building materials have become factors that cannot be ignored in building design. Among them, the selection of flame retardant sealant is very important. It can not only effectively prevent the spread of fire, but also has good adhesion to most building materials and does not require primer.
1. Advantages of fire retardant sealant
(1) Prevent the spread of fire
When encountering open flame, flame retardant sealant will form a stable carbonized layer, which is self-extinguishing and not easy to burn. Even if it encounters a fire source, it can be extinguished in a short time.
(2) Excellent high temperature resistance
Maintain stable performance at high temperature, do not become brittle, harden or crack, and do not decompose harmful gases when encountering high temperature, ensuring the safety of personnel.
(3) Excellent bonding performance
It has good adhesion to most building materials and can form strong bonding without primer.
2. Recommendation of high-quality fire retardant sealant
Tengyu TM513 flame retardant sealant is a one-component modified silicone sealant with flame retardant performance reaching FV-0 level. It is non-hazardous, and will not emit halogenated by-products under fire conditions.
(1) FV-0 flame retardant performance
In vertical tests, it can extinguish itself in a very short time and avoid continuous flame propagation and molten material dripping, preventing the spread of flame.
(2) Fire resistance rating up to four hours
(3) Anti-aging and weathering resistance
Excellent weathering characteristics, including resistance to ozone, UV radiation, and temperature extremes.
(4) Anti-displacement ability and good elasticity
MS flame retardant sealant has excellent elasticity (elongation can reach more than 350%)
(5) Wide range of application scenarios
- Fire-rated sealing and bonding application between many different construction materials
- Fire seal of movement and connection joints in floors
- Joints between prefabricated construction materials
- Fire stop sealing and bonding of ventilation ducts, gutters, and spouts for
- For expansion joints between pre-cast concrete panels
