Properties of the cured resin
The fully cured material has very good mechanical and dielectric properties, in particular high bond strength, even at elevated temperatures. The cured material also displays good chemical resistance.
Due to the product’s thermal properties this resin type can be used for thermal class 200 acc. DIN EN 60085.
Viscosity / Gel Time
When delivered, the viscosity of the resin compound comes to 1000 ± 150 mPa.s. In tanks it should be regularly monitored and maintained within the recommended limits. A Tank Sample Testing is available upon request.
Dobeckan ® ST NV 075-4475 can be processed in all conventional impregnating plants used for the above mentioned applications, like dip, trickle and flood methods, and VPI (Vacuum Pressure Impregnation).
When using this resin system care should be taken to ensure the resin is not exposed to components with surface temperatures in excess of 40°C.
During storage and processing the resin compound should also be kept away from direct sunlight and other sources of heat.
Curing of the resin should be carried out with current or preheated convection oven. When the trickle or dip-roll process is used, rotation of the objects has to be continued until the resin compound has been gelled, to avoid imbalances.
The indicated curing times are valid after the object has reached the curing temperatures.
It is necessary to follow the instructions of the Material Safety Data Sheet (MSDS) for this product.
