SynChem – Resins & Varnishes Damisol® 3630 VPI 02 1-component-resin
Damisol® 3630 VPI 02 is an opaque, solvent-free 1-component-resin based on unsaturated polyesterimides.
The thixotrop Damisol® 3630 VPI 02 has the following properties:
- no VOC (Volatile Organic Compound)
- very low smell
- high reactivity
- high stability in tank
Cured Damisol® 3630 VPI 02 has the following properties:
- high resin absorption
- outstanding thermal resistance (mechanical/electrical)
Application
Damisol® 3630 VPI 02 can be used for hot dipping and VPI of all kinds of windings, from any low/medium (3.3 kV) voltage rotating machines. Due to its high thermal resistance it could be used on any kind of electrical equipment exposed to high temperature conditions, as industrial motors and generators.
Standards
- UL-approved Class 180 (H)
- UL-file-no. E98 511
- RoHs compliant acc. 2011/65/EU
- VOC-free acc. 1999/13/EU
Delivery forms
Damisol® 3630 VPI 02 is available in:
- 20 kg cans
- 200 kg drums
- 1000 kg container
Storage
Damisol® 3630 VPI 02 can be stored minimum 12 months at max. 25 °C in sealed containers, protected from light and sun. Higher temperature can be achieved during short period of time.
Hardening
Recommended curing time:
2 h at 150 °C
Higher temperature and longer curing time will optimize the chemical resistance as well as the mechanical properties.
Protection
Refer to the material safety data sheet for complete information.
Processing
Damisol® 3630 VPI 02 can be processed on any kind of hot dipping or VPI equipment. The resin has to be protected from contamination. A regular viscosity check is necessary. Using the hot impregnating process, the resin temperature should be maintained lower than 30 °C and refresed with new resin. If storing the resin in a supply tank, we recommend keeping the resin under atmospheric pressure. It is advantageous not to fill the supply tank completely. The recommended filling level is 70 %.
