Chemax Tracit-300 Heat Transfer Cement

Heat Transfer Compound, Hardening

TRACIT-300 heat transfer compound (cement) hardens when cured. This product is recommended for use on steam, hot oil, and glycol heat tracing (tubing) installations where the upper temperature limit will not exceed 750°F (400°C). 

TRACIT-300 is used for high temperature process maintenance and freeze protection on straight run piping, valves, elbows, pumps, and flanges. This compound forms a highly conductive bond between the heater and process line. A single heat trace line installed with TRACIT-300 is equal to 3+ bare tracers. 

TRACIT-300 is also used with heating jackets, and with plate-type coil applications exceeding the temperature limits of our non-hardening compounds.

Coverage Rates

  • 30 linear feet per gallon when applied to 1/2" O.D. tracing at 1/8" thickness.
  • Flat surface (plate coil) coverage rate is 12 sq. ft. per gallon at 1/8" thickness. 

Installation Instructions

Using a pointing trowel, apply a thin layer (1/8"-1/4") between pipe line tracer and process pipe. Tracit-300 should fill in the air voids between the tracer and pipe. For maximum heat transfer, cover the top of the tracer, fully encasing it in the Tracit-300. Use Chemax CC1 Channels for quicker installation, weather protection, and less wasted material. It is optimal to remove loose paint, rust, scale, grease, etc. with wire brush before applying Tracit.

Cure Tracit-300 by air-drying (above 32°F) until hardened. Curing may be expedited by heating at low temperatures (under 200°F) for 4-10 hours. If application thickness exceeds an inch, apply compound in one-inch layers to reduce sagging. Allow Tracit-300 to cure between layer applications. No curing required when installing with Chemax CC1 Channels or with plate-type coil applications. 

When applying inside heating jackets, follow manufacturer's installation instructions.

Protect TRACIT-300 from moisture during installation. Do not expose to acid. 

Store at room temperature. Keep lid sealed tightly when not in use. If Tracit-300 has frozen, thaw before use. Use water or a putty knife for cleanup/removal.

Wear protective gloves and glasses when handling.
