Atom Adhesives AA-DUCT 902 Epoxy Adhesive and Coating
Categories:	Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive
Material Notes:	AA-DUCT 902 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 0-4 ohm•cm. A-DUCT 902 is also characterized by a wide operating temperature range from –50 to +170°C. A-DUCT 902 is recommended for electronic bonding and sealing applications that quire 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 Ration 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 Applications: Electrical, conductive, rmi/efi shielding, circuitry, printed circuit board and electronics repair Information provided by Atom Adhesives
