KM SEALER 2GE is a fire-resistant strip suitable to ensure the fire and smoke resistance in cracks for building joints in walls and concrete slabs.
KM SEALER 2GE is made up of a mineral fibre wool insert with graphitic thermo- expandable gasket KM-FF107. The strip is 52 mm thick; to seal structural joints in wall and concrete slabs up to 250 mm.
The strip is inserted, compressing it, into the opening of building joint. The thermo-expandable gasket must be in contact with one of the two sides of the joint. If necessary, the strip can be sealed with fire-proofing putty KM SEALER F. In case of fire, the intumescent gasket expands, clinging to the fibres of the strip, sealing the joint.
According to European standard UNI-EN 1366-3, EI 180 on masonry walls.
KM SEALER 2GE is a high resistant temperature and thermo-expanding strip building expansion joints. It is made up of a volcanic rock mineral fibre strip, covered on one side with a graphitic intumescent material KM-FF107. Compressible up to 50% of its original thickness.
To seal cracks in expansion joints in fire-resistant compartment structures: walls and concrete slabs.
The strip has excellent elasticity, excellent adhesiveness on many materials such as concrete, plaster, gypsum, masonry and metal.
