Stock Code:
SKU: product options

T-99 is a specialty heat transfer compound formulated to provide exceptional thermal stability and superior bonding strength up to 1832°F (1000°C).

 Maximum exposure temperature 1832°F (1000°C)

 Advantages:

  • Thermally stable at continuous temperature exposures up to 1832°F (1000°C)
  • Electrically non-conductive
  • Exceptional bond strength to resist thermal expansion and contraction
  • High shock resistance when exposed to extensive thermal cycling
  • Fine grain size and smooth texture for ease in workability
  • Water soluble for easy clean-up

T-99 is a specialty heat transfer compound formulated to provide exceptional thermal stability and superior bonding strength up to 1832°F (1000°C).

Unlike other grades of heat ransfer compounds, it is also electrically non-conductive.

It is supplied in a ready to use paste like form and may be applied by hand troweling to fill TFK channels.

T-99 resists thermal and mechanical shock and provides an efficient heat transfer rate with a high bonding capability. In
order to promote good surface wetting and intimate bonding, the surfaces of traced valves, pumps and other equipment
must be prepared just as though a paint or primer is to be applied. Oil, grease, dirt, rust scale, mill scale, etc., must
be removed. The use of solvents and emulsions along with craping, chipping and wire brushing are common pretreatment
techniques for steel surfaces.

T-99 heat transfer compounds are supplied in rugged resealable pails and have a standard shelf life of 1 year prior to opening. Compounds will harden when exposed to air or heat.
