3M Scotchcast Electrical Insulating Resin 4N, with nozzel and guard bag, is a 2 part, insulating and encapsulating, epoxy based, liquid resin that generates its own heat to cure. Compatible with solid/synthetic cable insulations and jackets, this resin makes an excellent insulator and sealer for cable splicing.3M Scotchcast Electrical Resin 4N A is a multi-purpose moisture sealing resin that remains stable, even at elevated temperatures. The resin bonds to itself and to nearly all modern cable jackets. It allows you to splice solid dielectric and oil filled cables up to 8 kV and to jacket high voltage splices. This resin is used in 82-AN, 82-B1N, 85-14-CPN and 90-B1N Series splice kits. ASTM Approved and RoHS 2011/65/EU Compliant .
