6201
Astro 6201 is a thixotropic, three-component polyester putty formulated with mica to enhance dielectric performance. It is designed for elevated-temperature curing in generator insulation systems.
This product is used as a “bar seal” to fill irregular shapes and voids prior to insulation taping of stator bars in large industrial motors and turbine generators.
Key Properties
- Long, proven track record of use in Class F (155°C) environments
- Malleable; can be sanded after curing to smooth surfaces prior to insulation taping
