Main features

  • 10-Minute Handling Time
  • Self-Leveling Flowable Placement
  • Fuel and Water Resistance

Product Description

LOCTITE® EA D609 is a two-part, ultra-clear epoxy adhesive for structural bonding applications requiring fast room-temperature curing. The low-viscosity, self-leveling system mixes at a 1:1 ratio by weight or volume and develops handling strength in approximately 10 minutes at 77°F. After full cure, the adhesive provides mechanical strength, electrical insulation, low shrinkage, and resistance to water, petroleum fuels, salt solutions, vapors, gases, and various organic and inorganic compounds. It is suitable for bonding supported substrates including metals, phenolic plastics, polyester, glass, ceramics, rubber, masonry, hardboard, forestry products, and other construction materials.

Key features

  • Fast room-temperature cure: Develops handling strength in approximately 10 minutes at 77°F and reaches full cure after 24 hours at 77°F.
  • Simple 1:1 mixing: Parts A and B mix at a 1:1 ratio by either weight or volume for cartridge or bulk application.
  • Clear, electrically insulating bond: The fully cured adhesive has a dielectric strength of 415 V/mil per ASTM D149.

Applications / Suitable for

  • Lower-temperature or wet industrial bonding applications
  • Fast-curing structural bonding
  • Bonding metals, phenolic plastics, polyester, glass, and glass fabrics
  • Bonding ceramics, rubber, masonry, hardboard, and forestry products

Pot Life
Pot life is the amount of time it takes for the viscosity of a material to double (or quadruple for lower viscosity materials) in room temperature after a material is mixed. It is closely related to work life but it is not application dependent, less precise and more of a general indication of how fast a system is going to cure.

Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
16.34 kV/mm
