3M ™ Epoxy Resins (281)
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.
