3M™ Scotchcast™ Electrical Resin 251 is a 2 part, oven curing, liquid resin that’s useful for electronic and electrical applications requiring the highest level of protection. This filled epoxy based resin has a medium viscosity property, which makes it easy to infuse on any surface. It is useful for applications that include filling, patching, insulating and more.
3M™ Scotchcast™ Electrical Resin 251 has good handling characteristics. The medium viscosity, rigid resin is suitable for applications where physical strength and excellent electrical properties at elevated temperatures are required. ASTM Approved, MIL I 16923E Certified and RoHS 2011/65/EU Compliant.
