Thermon T-80 | T-85: Heat transfer compound, Epoxi based
Stock Code:
SKU: product options

Low to medium temperature heat transfer compounds for use in moist and corrosive environment (typically around valves), not water-soluble.

Advantages:

  • Nonsoluble in water
  • No special curing required
  • Epoxy resin base creates strong mechanical bond
  • Suitable for moist or corrosive environments
  • 1/10-gallon cartridges allow easy application for valve and accessory heat tracing

T-80 and T-85 are low to medium temperature heat transfer compounds for use in moist and corrosive environments.

Thermon's heat transfer compounds provide an efficient thermal connection between the tracer and the process
equipment. By eliminating the air voids that would ordinarily exist, heat is directed into the pipe wall primarily through
conduction rather than convection and radiation. A single tracer utilizing Thermon's heat transfer compound has the
equivalent performance of three to five air convection (bare) tracers.

T-80 and T-85 are typically utilized around valves and quipment where maximum exposure temperatures will not
exceed 325°F (163°C) and 375°F (190°C) respectively. To educe installation time and product waste, these compounds
are available in 1/10-gallon (0.379-liter) cartridges.
