WEICON HT 300 adhesive and sealant is red, high-temperature resistant (+300 Deg.C/+572 Deg.F), free of solvents, strong, and has acetatecross-linking properties. It is resistant to weathering, ageing and chemicals and is extremely elastic (breaking elongation of approx. 300%). HT 300 is particularly suitable for heat-exposed bonds and seals and adheres very well to steel, aluminium, glass, ceramics and many additional materials. HT 300 can be used in industrial furnaces, flue gas systems, heating installations, exhaust gas routing, heating cabinets and in many additional areas.
Surface pre-treatment:
  • The surfaces must be clean and free of grease. Many surface contaminants, e.g. oil, dust and dirt, can be removed with WEICON Surface Cleaner. For heavily soiled metal surfaces, we recommend WEICON Cleaner Spray S; WEICON Sealant and Adhesive Remover is suitable for removing old paint or adhesive residues. Most materials can be bonded well to themselves and among each other. For certain materials or extreme requirements, we recommend the use of an adhesion agent (primer). Detailed information on this subject is contained in the primer selection table. A mechanical surface pre-treatment, e.g. sanding or sandblasting, can considerably improve the adhesion.
  • Processing cartridge
  • Application methods: Hand cartridge gun for 310 ml cartridges, compressed air gun (we recommend a variation with piston rod), automatic dosing systems.
  • Processing tube
  • Squeeze out by hand, close tube again immediately after use, opened tubes should be used up as quickly as possible.
  • Joining the parts to be bonded
  • To ensure optimum wetting, the parts must be joined before the first skin has been formed on the adhesive (skin-over time).
