Advantage:

Polyester modified silicone insulation impregnating varnish has good anti-humidity and drying properties,strong adhesion,high mechanical strength and lower curing temperature.

Application:

1054 Polyester Modified Silicone Resin Impregnated Varnishcan be used for impregnation of electric motors and electrical coils working in wet tropical, marine mining, traction, smelting, chemical and other environments..

Notice:

1. During slitting and use, edge gaps and cracks should be prevented to avoid tearing during operation and to avoid surface scratches, oil and dust pollution.

2. Store in an environment below 40℃, keep clean and dry, away from heat sources, and avoid direct sunlight.

3. The storage period is one year. If it exceeds the storage period, it can still be used if it passes the test according to the technical requirements.
