3M™ Scotchcast™ Electrical Insulating and Sealing Compound 2104 has a low gel point rating to ensure curing at room temperature. The high tensile strength of the resin exhibits a semi flexible property and good adhesion property after curing. It is ideal for electrical applications that need good handling and performance characteristics. High dielectric strength offers a very good electrical insulating property to the resin. The resin allows you to insulate conductors of multi core splices operating at 1 kV or less. It is used in 72 N, 85 Series kits. ASTM Approved and RoHS 2011/65/EU Compliant‎. 3M™ Scotchcast™ Electrical Insulating and Sealing Compound 2104 is a 2 part, liquid type, semi flexible resin useful for providing permanent splice protection. This polyurethane resin has a good wetting and impregnating property, which makes it easy to infuse on any surface. It is useful for applications that include filling, potting, sealing, insulating and more.
