Insulating Varnish

Insulating varnish is a protective dielectric coating used to insulate and seal electrical windings and components in motors, transformers, coils, and generators. It enhances electrical insulation, improves mechanical strength, and protects against moisture, chemicals, dust, and thermal stress. Typical technical characteristics include high dielectric strength, good thermal class rating, strong adhesion, resistance to vibration and abrasion, moisture resistance, and suitability for dip, brush, or spray application in electrical maintenance and manufacturing.
