    Drying & Cure Guide ▾

    Typical drying and curing information for 3GK electrical insulating varnishes. Times may vary depending on film thickness, component size, airflow and workshop conditions.

    Touch Dry

    15 min

    Surface becomes touch dry at approximately 21°C.

    Handleable

    45–60 min

    Components can usually be handled carefully after this stage.

    Full Cure

    24–48 hrs

    Full cure at ambient temperature for maximum developed properties.

    Heat Cure

    2–3 hrs

    Accelerated cure by heating components at approximately 80°C.

    Workshop note:
    Heavily taped, tightly wound or larger components may retain solvent for longer. Heat curing can help reduce the risk of solvent entrapment and speed up final cure.
    Application Method ▾

    3GK Red Anti-Tracking Varnish Spray is supplied in a convenient ready-to-use aerosol for fast, clean application. It's ideal for maintenance, electrical repairs and motor rewinding where brush or dip varnishing is impractical.

    Spray Application

    Apply light, even coats from approximately 20–30 cm away. Suitable for motors, coils, terminals, switchgear and electrical components where fast, convenient insulation protection is required.

    Application note:
    Shake the can thoroughly before use. Apply several light coats rather than one heavy coat, allowing adequate drying time between coats. Ensure surfaces are clean, dry and free from oil, grease and contaminants before spraying.
    Workshop Tips ▾

    Following good spray application practices helps produce a more consistent insulating coating, improved coverage and reliable electrical insulation performance.

    Shake Thoroughly

    Shake the aerosol well before use to ensure the varnish and pigments are evenly mixed for consistent coverage.

    Apply Light Coats

    Several light coats provide a smoother, more uniform finish than one heavy application and help minimise runs.

    Maintain Spray Distance

    Hold the can approximately 20–30 cm from the surface and use smooth, even passes for consistent coverage.

    Allow Drying Between Coats

    Allow adequate drying time between coats and always apply the product in a well-ventilated area away from ignition sources.

    Good workshop practice:
    Ensure the surface is clean, dry and free from oil, grease and contaminants before spraying. Drying times will vary depending on coating thickness, ambient temperature and humidity. Always allow the coating to fully cure before returning electrical equipment to service.
    Standards & Performance ▾

    The cured product conforms to BS EN 600464 Type 1.1 / IEC 600464.

    Dielectric Strength

    Tested to ASTM D115, with dielectric strength listed at 72 kV/mm for the cured varnish.

    Anti-Tracking Protection

    Designed to seal electrical leakage paths and help protect equipment from surface tracking in difficult environments.

    Performance note:
    Published performance data is based on the manufacturer's technical information for the Ultimeg 2000-372 anti-tracking enamel and varnish range. Actual performance will depend on surface preparation, application thickness, cure conditions and the operating environment.
    Frequently Asked Questions ▾
    Can I use 3GK Red Anti-Tracking Varnish Spray for motor rewinding?
    Yes. 3GK Red is suitable for electrical insulation applications including motor rewinding, coils, terminals, transformers and other electrical components requiring a protective anti-tracking coating.
    When should I choose an aerosol varnish instead of liquid varnish?
    Aerosol varnish is ideal for maintenance, touch-ups, small repairs and hard-to-reach areas. Liquid varnishes are better suited to dip impregnation, brush application and larger workshop or production jobs.
    How should I apply 3GK Red spray varnish?
    Ensure the surface is clean, dry and free from grease or contaminants. Shake the can thoroughly, then apply light, even coats from approximately 20–30 cm away. Several light coats are usually better than one heavy coat.
    How long does 3GK Red take to dry?
    Typical drying times are approximately 15 minutes touch dry, 45–60 minutes handleable and around 24–48 hours for full ambient cure. Drying time may vary depending on coating thickness, temperature, humidity and airflow.
    Why choose red anti-tracking varnish?
    Red varnish provides a visible protective coating, making it easier to identify treated areas during servicing, inspection and quality control. It is often chosen where visual confirmation of coating coverage is useful.
