Application

Dolphon® XL-2109 can be applied in roll-through and automatic machines.

Recommended cycle for roll-through application:

  • Pre-heat the windings to 70-80 °C.
  • Bring rapidly the windings to a temperature of 140 °C to gel the resin by Joule-effect.
  • Cure 30 min. at 150-160 °C by Joule-effect.
  • Complete the cure of the resin on the external part of the unit by UV-rays for 5-10 min.
