• Polymerized Low-Viscosity Silicone
  • Prevents Moisture penetration up to 1000°F (538°C)
  • 2 oz. bottles standard, 8 oz. available.

”Thermoseal” is a polymerized low-viscosity silicone fluid with proven ability to form a positive moisture barrier for mineral insulated thermo-couple and heater elements.

”Thermoseal” is absorbed into the pores of the mineral oxide insulating material, where after heat polymerization, it remains to prevent the penetration of moisture up to approximately 1000°F (538°C).

”Thermoseal” will not carbonize, therefore there is no loss of insulation value, should the seal area be exposed to greater than 1000°F (538°C). Numerous and extensive laboratory tests have proven the reliability of ”Thermoseal”

”Thermoseal” is supplied in standard 2 oz. bottles, 8 oz. bottles available.
