Applications

  • 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.

Properties

  • Heat-resistant, continuous exposure up to +300°C, short/intermittent exposure up to +350°C.
  • Durable, retains elasticity, maximum movement capacity of 25%.
  • Fast acetoxy-curing, solvent-freeCE-certified silicone system.
  • Excellent adhesion properties on many non-porous surfaces, such as metals.
  • Easy to work with, smooth application.
  • Good resistance to UV, weather, water, moisture and ageing.

Application conditions

  • Application temperature (ambient and surface) between +5°C and +40°C.
  • On stable, compatible, dry, clean, uncontaminated, grease-free and dust-free surfaces.
  • Ensure proper joint dimensions, for proper absorption of any movements.
  • Use a suitable brush to remove any loose particles from the surface.
  • Degrease the surface properly using Seal-it® 510 CLEANER.
  • Seal-it® 211 SILICON-HT has a broad bonding spectrum, but highly porous surfaces should be pre-treated with Seal-it® 520 PRIMER and non-porous surfaces with minimal bonding should be treated with Seal-it® 525 Clean & Bond.
  • Use Seal-it® 550 FINISH to apply a smooth and tight finish, before skin formation.
