Chemically Resistant adhesives

Atom Adhesives AA-DUCT 2979 Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: AA-DUCT 2979 is a fast curing one part epoxy adhesive with superior electrical conductivity and bonding capability. AA-DUCT 2979 has been shown to retain their properties through hundreds of hours of rapid temperature cycling and has also high impact absorption and stress resistance. These qualities make it an excellent choice for a number of electronic applications especially in "under the hood" and other harsh operating environments. AA-DUCT 2979 has a shelf life of at least 6 months when stored at -40°C. It contains no volatile, harmful solvents or lead, and conforms to all of the requirements of the solder replacement market.

Appearance: Silver

Cure Type: Heat cure

Mix Ratio by weight: 100:5/Resin:Hardener

Benefits:

  • High strength
  • Excellent mechanical, electrical properties
Substrates: Excellent choice for Integrated Circuits, aluminum, copper, magnesium, steel, bronze, nickel, ceramic, glass, phenolic and G-10 epoxy glass boards.

Typical Application: Applications where high impact absorption and stress resistance is required
