Impregnating and Encapsulating Resins for Transformers

Introducing UL electrical insulation system, ER7468, designed as single component heat cure for VPI (vacuum pressure impregnation) and dip/bake applications, provide complete impregnation of transformers and laminations.

The benefits of ER7468 are:

  • UL rated insulation system up to 220°C
  • Exceptional core noise and wire vibration reduction
  • Extremely flexible upon cure with outstanding bond strength
  • Excellent tank stability
  • 100% solids (No VOC)
  • Low viscosity
  • DOT non-hazardous
