For over 30 years, 3M™ Scotchcast™ Powder Epoxy Coatings have been used to electrically insulate coils, transformers, and motors. Literally hundreds of millions of electric motors have been produced over the years with Scotchcast resin coating the armatures and stators. Today Scotchcast resins have expanded into new insulation applications such as magnet wire, bus bars, and torroid cores.
