3M Scotchcast Polyurethane Resin
3M Scotchcast Resins are 100% solids, thermosetting, electrical-grade insulating resins. Classified chemically as either epoxy resins or polyurethane resins, the product line includes two-part epoxy liquids and two part polyurethane liquids. 3M Resins unique electrical and physical properties make them ideal for insulating and protecting electrical/electronic parts and assemblies. Their physical features also make them suitable for non-electrical, general use applications; for example, as adhesives and sealants. Polyurethane Resin 226 is used for a wide range of electrical and electronic potting and casting applications. For example, its low exotherm and low cure shrinkage, make possible the potting of small, heat-sensitive components, as well as the casting of large quantities of the resin at one time. And the very low viscosity of the product makes it possible to quickly fill and impregnate sand-filled modules.
