Epoxy Automotive Assembly Adhesives

Epoxy adhesives generally tend to be viscous liquids or pastes, although self-leveling liquids are available. In general, epoxies are less sensitive to slight variations in mix ratio. Also, epoxy adhesives offer long open times, allowing for repositioning and assembly of complex shapes. Final properties develop within 24 hours at room temperature.

  • Two components or "parts":
    • Resin (A-Side)
    • Hardener (B-Side)
  • Uncured properties:
    • Low odor
    • Tend to be very viscous liquids or pastes
  • Application properties:
    • Different mix ratios may be specified depending on desired final physical properties
    • Relatively unaffected by humidity while curing
    • Tend to have slower cure rates (with a few exceptions)
      • Cure rate can be accelerated dramatically with heat
  • Cured properties:
    • Relatively low elongation (often considered rigid in comparison to acrylics and urethanes)
    • Good high temperature strength - chemically stable up to 125°C (250°F) and some even to 200°C (400°F)
    • Very good chemical resistance
    • Bonds well to porous substrates
    • Good adhesion to a wide variety of materials, but surfaces should be very clean
