Tracit-1000

Heat Transfer Compound, Non-Hardening

Non-hardening TRACIT-1000 heat transfer compound was designed for use on externally cooled tanks and vessels. This product is applied to plate or clamp-on coils before installation on the tank. TRACIT-1000 eliminates the air voids that exist between the coil and vessel wall, transferring heat far more efficiently by means of conduction. Plate-type coils installed with TRACIT-1000 experience up to a tenfold increase in heat transfer rates.


TRACIT-1000 is non-setting and can be easily removed from installations. This mastic maintains excellent surface contact during expansion and contraction cycles. TRACIT-1000 heat transfer mastic is water-resistant and does not have to be protected from moisture or rain.

Installation Instructions

No premixing or curing required. Using a hand trowel, apply a thin layer (1/8"-1/4") to mechanically mounted surfaces (such as clamp-on coils) to fill in air gaps to ensure contact with heating source. If installing in a cold environment, product may be warmed up to 80°F for lower viscosity and easier application. Product may be applied over existing coatings, although excessive surface dirt and rust should be removed for ideal performance.


TRACIT-1000 heat transfer cement will act as a corrosion barrier.  


TRACIT-1000 should not be exposed to open flames or strong oxidizing agents.  If removal is necessary, scrape off using a hand trowel and an industrial degreasing agent.   


Wear protective gloves and glasses when handling.
