SynChem – Resins & Varnishes 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
Application
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.
Standards
- Thermal class H (UL 1446) / E98511
Delivery forms
Damisol® 3500 LoV is available in:
- 20 kg cans
- 200 kg drums
- 1000 kg container
Storage
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. Protect from light, sun and heat.
Hardening
The curing time is 2.5 h at 170 °C. The exact curing time depends on different parameters.
Protection
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.
Processing
The most commonly used processes are atmospheric impregnation and vacuum pressure impregnation (VPI). However, the good stability of the resin also allows processing at elevated temperatures (dipping, rolling and trickling processes). With the "hot dipping process", the engine can be heated up to 90 °C before impregnation.
