Operating Temperature Range
Tests have confirmed that Thermstrate TC can be used reliably
up to 150°C.
Surface Conditions
Typical interface surface conditions are quoted below:
Surface finish
1.6 microns or better
Surface flatness
.001 cm/cm or better
General Information
For safe handling information on this product, consult the
Material Safety Data Sheet, (MSDS).
Thermstrate TC is completely reworkable. No foreign residue
remains after disassembly. If, due to the need for repair or
rework of the installation, a second application of the
Thermstrate TC can be made without the need for cleaning of
interface surfaces. If a clean surface is required, any residual
phase change compound present can be easily removed with
mineral spirits.
While Thermstrate TC is supplied as a convenient to use
applicator bar, pretooled pads are available for over one
thousand commonly used electronic devices. Thermstrate
2000 may be available as single die cut pads, on multi-pad
sheets, or on continuous rolls for high volume production
Application Recommendations
Reasonable flatness and surface conditions should apply to
both mating surfaces. Flatness specification for one mating
surface of 0.002 in/in is typical of a reasonable flatness and
finish specifications work well with this product.
These applicator bars are designed in a width that has been
highly successful as a low-cost application for microprocessor
heat sinks. They are typically used with one “swipe” to make a
very acceptable compound application of appropriate thickness
and consistency for typical microprocessor heat sinks.
Application of this material should be simple with little
requirement for repeated application on the same surface. No
dispensing or squeegeeing equipment is required.
The TC Applicator Bar can be used on an unlimited variety of
heat sinks, cold plates, or other component designs,
maximizing flexibility. They are intended to be used to deliver
a minimum coating thickness on any heat transfer device.
Complete directions for use are available via contact with
Loctite Laguna Hills, CA at (949) 582-6712.
Prior to assembly products shall ideally be stored in a cool, dry
location in original packaging at temperatures below 40°C
(104°F). Under these conditions the shelf life is indefinite.
Thermstrate can be applied to heat sinks which are then
shipped to a final assembly location as long as the temperature
does not exceed that stated above.
