ARALDITE® 2019 (AW 4859 / HW 4859)

ARALDITE® 2019 adhesive combines the properties of high-temperature resistance and toughness for high-end carbon composites bonding.

Perfect for creating innovative, lightweight products.

​Product benefits

  • Bonds carbon composites
  • High temperature resistance
  • High toughness and resilience
  • High lap shear strength
  • Contains spacers to ensure a minimum bond line thickness of 0.05 mm

​Application areas

  • Lightweight cars
  • Speedboats
  • Drones

Performance Specifications

  • Two-component Epoxy Technology
  • 100 mins Pot life at RT
  • 4.5 hrs Fixture time at RT
  • ^ 35 MPa / 5,076 psi Shear strength on composites at RT
  • 140°C / 284°F Maximum continuous operating temperature*
  • 40 MPa / 5,801 psi Tensile strength
  • 1 600 MPa / 232,060 psi Tensile modulus
  • ca. 4.3% Elongation at break

* For the maximum continuous operating temperature, we consider the maximum temperature for which the residual lap shear strength is 1/3 of the lap shear strength at room temperature or the temperature for which the residual lap shear strength is 5 MPa.
