Introduction of MF840 two-component polysulfide insulating glass special sealant series
MF-840 two-component polysulfide insulating glass special sealant series (hereinafter referred to as MF-840 series) is a solvent-free, two-component, room temperature curing elastic sealant, suitable for glass, aluminum alloy, galvanized steel, and other materials Has excellent bonding properties.
MF840 series sealant is composed of two components A and B. The A component (base paste) is a white uniform and delicate paste, and the B component (vulcanized paste) is a black uniform and delicate paste. Use ratio, A component: B component = (mass ratio) 100: (6-12), the best use ratio is 100:10.
MF840 series sealant is mainly used to make insulating glass.
Insulating glass: two or more pieces of glass are effectively supported and evenly separated and bonded and sealed around the periphery, so that a dry gas space is formed between the glass layers.
MF840 series sealant can be used with butyl sealant: butyl is the first seal and polysulfide is the second seal (outer seal); it can also be used to seal single-channel insulating glass.
The role of MF840 series sealant in insulating glass unit:
Structural support for insulating glass
Seal the hollow cavity to prevent outside water vapor from entering
The typical phenomenon of insulating glass failure is condensation and water ingress in the insulating glass spacer layer, which not only affects the appearance of the entire glass, but also affects the thermal performance of the entire glass.
The reason for the failure of the insulating glass: The first and second sealant of the insulating glass have lost the ability to block the external water vapor from entering the cavity. The glass self-explodes.
-Insulating glass failure phenomenon-fog
-Insulating glass failure phenomenon-frost
-Insulating glass failure phenomenon-air leakage and water leakage
