DEFINITION OF ACE-56153 TWO COMPONENT ADHESIVE
ACE-56153, a two component electrically conductive adhesive low viscosity, room temperature curing, high strength, gap filling, silver-filled epoxy adhesive, that has been formulated to meet the demanding requirement of Federal Specification, MMM-A-1931 (9/19/75), Type I. ACE-56153 cures to specification in 24 hours at 22±1ºC. ACE-56153, when cured at elevated temperature, or for longer times at room temperature, display volume resistivity values 10 to 100 times lower than those required by the specification. ACE-56153 has a light paste consistency that allows for dispensing by pneumatic dispensers, it is available in mixer packs for field applications and in bulk or in premixed and frozen packages.

TYPICAL PROPERTIES OF CURED ACE-56153 TWO COMPONENT ADHESIVE
The properties listed below were determined from measurements carried out in a limited number of tests after curing ACE-56153 for 24 hours at 25°C. These properties are given as guidance, and do not constitute a guarantee. It will be for the user, in all cases, to carry out their own tests to determine weather ACE-56153 is suitable for the users particular application.
