Directions for Use
TBS is especially useful in the manufacture of heat sink assemblies where ‘piggy back’ arrangements are
applied and where the manufactured design of heat sinks does not allow for welding or brazing techniques to be
employed due to complexity or geometry of the fins. Bare metal parts and heat sinks can be coated with TBS to
avoid the risk of short circuiting if they contact other parts due to vibration damage. Chassis assemblies can be
used as heat sinks by coating them with TBS and mounting components on them - the chassis can still be
earthed.
Surfaces must be clean and dry and free from grease, dust and contaminants. Electrolube manufacture a range
of solvent and water based cleaning solutions for the preparation of surfaces prior to application. Mix the two
parts of the compound together (as per the mix ratio given above). Apply to one of the prepared surfaces using
a clean instrument, ensuring a thin even coating is achieved. Press the two surfaces together firmly (1-2 bars is
adequate and a pressure of over 6 bar should not be applied). The mixture will remain flexible to allow for
positioning adjustments to be made at this stage if necessary. For full cure, please follow the instructions above.
Additional Information
There are many methods of measuring thermal conductivity, resulting in large variances in results. Electrolube
utilise a heat flow method which takes into account the surface resistance of the test substrate, thus offering
highly accurate results of true thermal conductivity. Some alternative methods do not account for such surface
resistance and can create the illusion of higher thermal conductivity. Therefore, when comparing thermal
conductivity measurements it is important to know what test method has been utilised. For more information
please contact the Electrolube Technical Department.
The rate at which heat flows is dependent on the temperature differential, the thickness and uniformity of the
layer, and the thermal conductivity of the material. Products with the same comparable thermal conductivity
value may have very different efficiencies of heat transfer in the end application depending on how successfully
a thin even film can be applied.
A full range of heat transfer products are available from Electrolube: standard and highly thermal conductive
pastes (HTC, HTSP, etc.), gap filling materials (HTCPX), Silicone RTVs (TCOR, TCER) and encapsulation
resins (ER2220, UR5633, SC2003).
