Stress Grade
Composition: The paint consists of mixture of semi conducting filler in a specially modified phenolic resin.
Non-linear voltage-current characteristics make it suitable for end corona protection for high voltage rotating electrical machine. The paint can be applied on the high voltage stator coil / bar using brush. The required properties are achieved when the paint attains complete dry condition.
The Paint can be used for Resin rich/Resin poor insulation systems as voltage gradient on the overhang part of high voltage coils/ bars for HV machines. Thin & uniform coating should be applied by brush. In case of multiple coating, at least 30 minutes time gap to be allowed for drying of previous layer.
The paint must be stirred & mixed thoroughly before application as it contains heavy particles having tendency to quickly settle down. If necessary, MEK or other compatible solvent can be used as thinner to get required consistency of paint during its application. The paint must be stored sealed original containers in controlled atmosphere.
In metal containers 1 kg & 5 kg
Minimum 12 months at ≤ 25°C in sealed container.
