3M Scotchcast Electrical Insulating Resin 2104 is a 2 part, liquid type, semi-flexible resin useful for providing permanent splice repair and 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, repairing and more.3M Scotchcast Electrical Insulating Resin 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 3M Scotchcast Inline Splice Kits 72-N Series and 3M Scotchcast Multi-Mold Resin Splice Kits 85 Series. ASTM Approved and RoHS 2011/65/EU Compliant .
