Damisol® 3500 LoV 1-component-resin

Damisol® 3500 LoV is a Freon resistant heat curing epoxy resin with low viscosity.


Damisol® 3500 LoV has the following properties:

  • low viscosity
  • Freon resistant
  • very low VOC emission
  • suitable for dipping- and vacuum-impregnating processes
  • excellent long-term heat resistance

Damisol® 3500 LoV is mainly used for the impregnation of medium and low voltage industrial motors. Due to the very good electrical, mechanical and thermal properties of Damisol® 3500 LoV it is also suitable for traction motors and transformers.

  • Thermal class H (UL 1446)
Delivery forms

Damisol® 3500 LoV is available in:

  • 25 kg cans
  • 200 kg drums
  • 900 kg container

Damisol® 3500 LoV can be stored 12 months in sealed containers at room temperature (max. 25 °C). Higher temperature can be reached during short period of time. If storing the resin in a supply tank, dry air or "Nitrogen" is recommended.


The curing time is between 5 h at 160 °C and 2 h at 170 °C. The exact curing time depends on different parameters.


Please avoid contact of Damisol® 3500 LoV with skin. Use safety gloves and glasses.

Please refer to the material safety data sheet for complete information.


The most frequent processes are atmospheric dipping as well as VPI.
