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.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.
