3M Scotchcast electrical resin 2131 is a 2-part, flame-retardant compound, useful for coating cable jackets when splicing or repairing mine and portable cables. This permanent, polyurethane, liquid type resin has a unique formulation to use in rugged conditions. High dielectric strength offers a very good electrical insulating property to the resin. 3M Scotchcast flame-retardant resin 2131 has 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 applications that need excellent thermal shock and mechanical shock-resistance. It has a high flash point, helping prevent any fire hazard due to quick ignition. The flame-retardant resin allows you to insulate cable splices operating up to 1 kV and to seal the crotch or sheath when terminating multi core cables. ASTM and MSHA approved, RoHS 2011/65/EU compliant.
