The Scotchcast™ Resin 280 system remains flexible even after prolonged heat aging, while its low viscosity and fine wetting properties allow complete impregnation of fine wires in coils. These include impregnation and encapsulation of coils, transformers, strain-sensitive circuitry, modules and other electrical and electronic components. - 3M™ Scotchcast™ electrical resin 280 is characterized by a high-temperature rating, outstanding physical and electrical stability and superior resistance to moisture. Scotchcast Resin 280 can be cured at 65 °C and still exhibit excellent electrical properties in applications where components require low temperature cures.
