FernoTherm Coating

FernoTherm Coating

Fernotherm Coating is a fire-retardant coating that expands when exposed to fire. It is developed to enhance the fire resistance of fire seals by protecting electric cables, cable trays, and metal pipes. The coating protects the plastic sheath of the cable and, therefore, secures the power supply during a fire. Fernotherm coating insulates the cables during a fire, thereby increasing the overall fire resistance.

Properties

  • Prevents damage from fire and smoke
  • The intumescent coating expands slightly and has an endothermic effect in case of fire
  • Smoke, gas, and vapor-tight
  • Suitable without the use of a primer for materials such as cables with a PVC and rubber jacket, for steel and primed steel, for most non-porous materials such as concrete, brick, masonry, wood, and plaster
  • After applying a protective topcoat, Fernotherm coating can also be used for outdoor applications.
  • White in colour and permanently elastic
  • Does not affect cables and pipes
  • Formaldehyde and halogen-free
  • Resistant to aging
  • Environmentally friendly
