3M Scotchcast™ 241 Semiflexible Polyurethane Electrical Resin, 14 lb, Brown

ID: 3MR24114LB Mfr ID: 3MR24114LB
Manufactured by: 3M Electrical OEM Materials
Resin 243 is identical to 241, except it is unpigmented so it can be colored at any shade desired. This general purpose resin system has built-in flexibility, good adhesion, terminal shock and impact resistance, and stable electrical and physical properties at 130 deg C (Class B) continuous operation. This filled resin system is used where higher thermal conductivity and greater mechanical strength are required.
