How To Use Red Insulating Varnish?

Red insulating varnish is an alkyd resin with exceptional dielectric strength, used to electrically isolate conductors in windings and coils. It is applied like a conventional paint, by dipping, brushing and spray. However, the sheer size of some motors renders these methods unfeasible. In such circumstances, vacuum impregnation is employed, where large vacuums transfer liquid resin from a holding tank to a coating chamber, essentially encapsulating exposed wires.


One of the desirable attributes of a paint job is less filming, as thicker paint is more prone to damage and, in most cases, ages faster. The enamel base is thicker and softer than the thin, hard polyester base. Enamel base is like two coats of paint while polyester base is like one coat when it comes to foundation/clear work.
