Two Component Electrically Conductive Adhesive

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.
