Product Description

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. GENERAL PROPERTIES Appearance Grey Cure Type Heat cure or Room temperature Benefits High strength Perfect bond Cold solder for heat sensitive components Mix Ratio by weight 10/05 / Resin/Hardener Substrates Excellent choice aluminum, copper, magnesium, steel, bronze, nickel, kovar, ceramic, glass, phenolic and G-10 epoxy glass boards.
