Material Notes:
3M Scotchcast Electrical Resin 260 is a widely used, well-known general purpose epoxy powder resin. A one-part, green pigmented, rapid heat-curing product, it is designed to provide a continuous, tough, moisture and chemical resistant dielectric coating to a variety of substrates. Resin 260 is manufactured by a fusion blend process, insuring that each individual particle of powder contains all the components necessary to effect a complete cure and attain stated performance properties. Resin 260 is applied to an object that has been heated to a temperature above the melting point to the resin. On contact with the preheated application surface, the resin melts, flows to a controlled extent, then cures, bonding to the substrate and coalescing into a smooth, continuous, essentially uniform thick coating. It effectively coats flat surfaces and corners, as well as high points. Uses for resin 260 include moisture-proofing and insulating armatures, stators, buss bars and toroid cores.Information provided by 3M
