T-3 heat transfer compound creates an efficient thermal bond between a steam or electric heater and process pipes or equipment. A single "Thermonized TM"steam tracer utilizing Thermon's heat transfer compound is more cost effective than a contoured clamp-on jacket and has the equivalent performance of three or more bare tracers.

T-3 is typically utilized for applications with maximum exposure temperatures of 700°F (371°C).

To minimize waste and speed installation, use Thermon's ChannelTraceTM system featuring TFK channels. The ChannelTrace system provides protection prior to installation of thermal insulation and requires no special curing procedure for the T-3 heat transfer compound under the TFK channel.
