Heat Transfer Compounds
Compound Preparation . . .
1. Prior to installing compound, review the minimum applica-
tion temperature limits listed below.
Surface Preparation . . .
1. Surface areas where heat transfer compound is to be in-
stalled must be reasonably clean. Dirt, rust and scale can
be removed with a wire brush. Oil and grease films should
be removed with a solvent. Mill varnish and protective
coatings may be removed with a suitable stripper.
2. If T-3 is to be installed on aluminum surfaces, Thermon
ALP primer should be applied to the surface prior to instal-
lation.
Curing Procedures . . .
1. ChannelTrace TM or hand-troweled applications using T-3 or
T-99 grades require curing within 60 days of installation.
2. For T-3 and T-99 hand-troweled applications, the com-
pound must be cured for 4 to 12 hours at 70°C to 100°C.
Use copper or stainless steel tubing tracers. Carbon steel
tubing tracers are not recommended unless curing takes
place immediately.
3. T-80 and T-85 at room temperatures up to 65°C may
remain tacky for months. This does not change the heat
transfer characteristics of the compound. T-80 and T-85
cure in 4 to 12 hours at temperatures between 100°C and
165°C.
4. T-802 grade, when mixed one part B to two parts J, cures
in 1.25 to 4 hours between 15°C and 40°C.
5. SnapTrace, EFS-1, T-80, T-85, T-802 and Non-hardening
compounds may be put into operation immediately—no
curing procedures required.
Precautionary and Cleanup Measures . . .
1. Wearing gloves and safety glasses is a must.
2. T-3 and T-99 grades are slightly alkaline and should be
kept away from eyes.
3. Waterless soap may be used to remove compounds from
hands, arms, etc.
4. When using T-80, T-85, NH or T-802, equipment and
spillages should be cleaned using suitable hydrocarbon
solvents.

2. Moderate freezing temperatures will not damage the com-
pound. However, it is recommended that the compound
be stored in a heated room for eight hours prior to use.
Storage and Handling . . .
1. T-3 and T-99 grades are air-setting products with a shelf
life of one year. Store at room temperatures below 65°C.
These grades freeze at -1°C; however, freezing will not
damage compound. Frozen compound should be heated
to a temperature above freezing before
installation.
2. Cartridges of T-80 and T-85 grades stored at average
room temperatures above 5°C have a shelf life of 90 days.
Refrigerate these grades below 5°C to extend shelf life to
one year. 3.78 I and 18.9 I cans have a 30-day shelf life.
3. SnapTrace is non-aging but should be stored at room tem-
peratures below 50°C.
