ATE-46440

DEFINITION

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.

APPLICATION PROPERTIES

  • 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.

TYPICAL PROPERTIES OF THE CURED SYSTEM

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.
