ATE-46440 is a thermally conductive, low heat curing adhesive for heat sinks and other applications where a high degree of thermal conductivity is required.
This product is designed for applications which are exposed to high heat (≥ 200°C) during post manufacturing steps such as heat cure powder coating.


  • Check ATE-46440 Part A for filler settling. If filler settling has occurred, warm to 100°F and mix with spatula or other suitable device such as paint blade or shaker.
  • To prepare small quantities of ATE-46440 (100 g or less) add Part B to Part A at about 38°C (100°F), mix thoroughly then vacuum degas at 0.5mm Hg or let stand at room temperature for 10-15 minutes before using.
  • For larger amounts of ATE-46440, spread the mixed material onto a horizontal plate or surface, no thicker the 1/4 inch, and let stand until most air has escaped, or degas the mixed material at 0.5 mm Hg in a container 3-4 times larger than the volume mixed.
  • Since the cure reaction is exothermic, never mix more than 2,000 g of ATE-46440 at one time. Once a large batch is mixed the ATE-46440 must be used within 30 minutes after mixing; otherwise, a dangerous exotherm may develop!! Any questions about this, please contact Protavic America, Inc.


The properties set out below were obtained after curing for 24 hours at 25°C. They were determined following measurements carried out in the laboratory over a small number of tests. They are values given by way of guidance, and do not constitute a guarantee. It will be for the user, in all cases, to carry out their own tests to determine whether ATE-46440 can be used for the particular application they have in mind.
