  • Specially developed as a durable heat-resistant, low-compression gasket compound for machinery and engine parts.
  • Heat-resistant sealant for devices and equipment, such as pumps, generators, thermostats, hotplates, stoves, oven parts, boilers, water heaters, central heating units and other heating elements.
  • Heat-resistant sealant, specially designed for installation work in the construction and industrial sectors, such as seals on hot water pipes and hot air ducts/pipes, adapters/fittings, smoke and air exhaust ducts, etc.

  • Good resistance to UV, weather, water, moisture and ageing.

Application conditions

  • Application temperature (ambient and surface) between +5°C and +40°C.
