3M Scotchcast ™ Electrical Resin 281 is a Two-Part, Semi-Flexible, Filled, Epoxy Liquid Resin which is characterised by its high temperature rating, electrical stability, and excellent retention of flexibility, even after prolonged heat
aging. Scotchcast ™ Epoxy Resin 281 can be cured at low temperatures, but the optimum properties are obtained
with the higher temperature cure schedules.

  • High temperature rating (155ºC – Class F)

  • Low temperature curing

  • High thermal conductivity

  • 3M Scotchcast Resin 281 is ideal for the impregnation and encapsulation of coils, transformers, motors and other electrical and electronic components.

  • 3M Scotchcast Resin 281 should be used instead of
    Scotchcast Resin 241 where greater mechanical strength, higher tensile strength, better thermal shock and higher thermal conductivity are required.
