ATE-46446 Thermally Conductive Adhesive

DEFINITION OF ATE-46446

ATE-46446 is a thermally conductive, room temperature curing adhesive for Bonded heat sinks and other applications where a high degree of thermal conductivity is required.

APPLICATION PROPERTIES

  • Check ATE-46446 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-46446 (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-46446, 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 29 inches 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-
    46446 at one time. Once a large batch is mixed the ATE-46446 must be used
    within 30 minutes after mixing; otherwise, a dangerous exotherm may develop!!

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-46446 can be used for the particular application they have in mind.
