Atom Adhesives AA-DUCT 903 Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: AA-DUCT 903 is an epoxy adhesive and coating formulation based on Nickel. This epoxy nickel formulation offers the maximum continuity of conductivity with an electrical resistivity value of less than 3.8x10-2 ohm-cm. AA-DUCT 903 is recommended for electronic bonding and sealing applications that require both fine electrical and mechanical properties. AA-DUCT 903 has been used extensively in such diversified applications as microwave EMI & RFI shielding, in the assembly or repair of printed circuit boards, wave guides, electronic modules, flat cable, high frequency shields, connections, circuitry and as a cold solder for high-sensitive components where hot-soldering is impractical.

Appearance: Gray

Cure Type: Heat cure or Room Temperature

Benefits:

  • High strength
  • Perfect bond
  • Cold solder for high-sensitive components
Mix Ratio by weight: 100:5/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
