3M™ Scotchcast™ Electrical Resin 280 is characterized by a high temperature rating, outstanding physical and electrical stability and superior resistance to moisture. Resin system 280 remains flexible even after prolonged heat aging, while its low viscosity and fine wetting properties allow complete impregnation of fine wires in coils. Resin 280 is well suited to impregnating, potting and encapsulating applications that require superior electrical performance, maximum resistance to moisture and thermal shock resistance. Gel time is 20 min at 121(deg)C.
