Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Product Highlights:
  • Silver filled, electrically conductive
  • Cryogenic service
  • Superb mechanical strength properties
  • First-rate peel strength
  • Capable of passing NASA low outgassing
  • Unlimited working life at room temperature
Kohesi Bond TUF 1820 HTS is a toughened, single component, silver conductive epoxy system that requires no mixing and offers an unlimited working life at room temperature. This product offers high electrical as well as thermal conductivity. It cures in 60 - 80 minutes at 120°C and even faster at higher temperatures. TUF 1820 HTS offers an extremely wide service temperature range of 4K (-269.15°C) to +200°C. This product can withstand severe thermal cycling and shocks even at cryogenic temperatures. Being a one component system, it provides ease of application and also adheres well to a wide variety of substrates including metals, ceramics, composites, most plastics and glass. It provides superior bonding and physical strength properties as well as outstanding dimensional stability. TUF 1820 HTS is a 100% solids and a reactive system i.e. it does not contain any solvents or diluents. It has a silver gray color. It also extends first-rate chemical resistance to a variety of acids, bases, fuels and water. It is capable of passing NASA low outgassing test. TUF 1820 HTS is widely used in demanding electronics, optoelectronic, aerospace, specialty OEM and various vacuum based applications.
