* Gallium is known to alloy with various other metals. TC4 should be tested in your individual application to ensure long term reliability.
** Calculated based on industry data and measurements from testing in the Chip Quik laboratory, using proprietary modified hot plate test method, using 12.7mm (0.5") diameter copper substrates, with TC4 liquid metal thermal interface material (TIM) applied between substrates in a fine layer.
Academic research into Gallium based liquid metal alloys, using laser flash test method, has shown thermal conductivities of up to 350 W/mK can be achieved in ideal laboratory conditions when a small enough quantity, less than 0.01g, of liquid metal is applied to fill all microscopic air gaps between copper substrates. This is very close to the thermal conductivity of the pure copper substrates of 385 W/mK.
Thermal conductivity of liquid metal is highly dependent on application, quantity used, pressure, substrate material and any coatings applied. Testing in end use application is required to determine actual thermal conductivity achieved in application, as it may be higher or lower than 79 W/mK, dependent on a large number of application specific factors.
Application Instructions
Apply sparingly with provided tips. Thinly spread using provided squeegee. Deep-Space Liquid Metal™ is highly conductive and is designed to fill all small cracks and crevices in surfaces to achieve extremely high thermal conductivity. Deep-Space Liquid Metal™ is thermally and electrically conductive, avoid getting it on electrical pins/pads/traces/BGA balls.
Storage and Handling
Store at room temperature 20-25C (68-77F).
Shelf Life
>60 months
Transportation
This product has no shipping restrictions. Shipping below 0C (32F) or above 25C (77F) for normal transit times by ground or air will not impact this product's stated shelf life.
