Atom Adhesives AA-DUCT 902LP Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: AA-DUCT 902LP is an epoxy adhesive and coating formulation based on pure silver. This versatile silver formulation offers the maximum continuity of conductivity with an electrical resistivity value of less than 1x10-4 ohm-cm. AA-DUCT 902LP is also characterized by a wide operating temperature range from –50 to +170°C. AA-DUCT 902LP is recommended for electronic bonding and sealing applications that require both fine electrical and mechanical properties.

Appearance: Silver

Cure Type: Heat cure or Room Temperature

Benefits:

  • High strength
  • Perfect bond
  • Cold solder for heat sensitive components
Mix Ratio by weight: 100:6/Resin:Hardener

Substrates: Excellent choice aluminum, copper, magnesium, steel, bronze, nickel, kovar, ceramic, glass, phenolic and G-10 epoxy glass boards.

Typical Application: Electrical, conductive, rmi/efi shielding, circuitry, printed circuit board and electronics repair
