3M™ Scotchcast™ Electrical Resin 260 is a 1 part, powder resin used for coating flat surfaces, corners, and high points. This general-purpose epoxy-based, powder resin has a very low viscosity property, which makes it easy to infuse on any surface. The resin melts when it’s heated, it flows to a controlled extent and then cures, bonding to the surface in a uniform, thick coating.
3M™ Scotchcast™ Electrical Resin 260 has a low gel point rating to ensure a quick curing process. The resin is made from a fusion blend process which offers the components necessary to provide a complete cure and meet required performance properties. It provides a continuous, tough moisture and chemical resistant dielectric coating to a variety of substrates. It is ideal for applications that need excellent thermal shock and mechanical shock resistance. Its high dielectric strength offers excellent electrical insulating property to the resin, thus making it an ideal insulator for creating a barrier between 2 conductors. UL Listed and RoHS 2011/65/EU Compliant.
