Description

• • Motor Rewinding Varnish – Farmas Type

    Motor Rewinding Varnish (Farmas) is a high-quality insulating varnish specifically designed for use in the rewinding and repair of electric motors, transformers, coils, and other electro-mechanical components. Known for its strong adhesion, high dielectric strength, and heat resistance, this varnish ensures long-term protection of motor windings by enhancing insulation and preventing moisture ingress, vibration damage, and short circuits.

    Farmas-type varnish is typically used in the dip-and-bake or air-dry process after copper winding, sealing the windings and filling air gaps to improve mechanical integrity and electrical performance. It is available in both solvent-based and solventless versions, with common colors being red, brown, or clear.

    Key Features:

    • Excellent Dielectric Strength: Provides effective electrical insulation and reduces the risk of shorts and breakdowns.

    • High Heat Resistance: Withstands operational temperatures typically in Class B (130°C) to Class H (180°C), depending on the formulation.

    • Strong Adhesion: Bonds firmly to copper windings, core metal, and insulation papers.

    • Moisture & Chemical Protection: Forms a protective barrier against humidity, oil, and other contaminants.

    • Low Viscosity: Ensures deep penetration into windings for thorough coverage.

    • Fast Drying Options: Available in both air-drying and oven-curing grades for workshop convenience.
