  • 1 Time to double initial mixed viscosity.
  • 2 Cure time for 3 mm thickness at 20 °C (68 °F) and 55 % relative humidity.
  • 3 Time to 90 percent of final hardness and adhesion or 90 % of curve height for elastic modulus; additional time may be required for the part to warm to near oven temperature.
  • 4 Time to 90 percent of final hardness and adhesion or 90 % of curve height for elastic modulus; additional time may be required for the part to warm to near oven temperature.
  • 5 Time to 90 percent of final hardness and adhesion or 90 % of curve height for elastic modulus; additional time may be required for the part to warm to near oven temperature.
  • 6 Thermal Conductivity at 25 ºC (77 ºF)
