Thermally Conductive 50-3150FR with Catalyst 12 Now UL 94V-0 Listed

The 50-3150FR with catalyst 12 has been a trusted high performance thermally conductive epoxy potting compound for decades. The 50-3150FR with catalyst 12 is UL 94V-0 listed (File Number E235584), which is a common flame retardant requirement for power electronics and automotive/electric vehicle applications..

With catalyst 12, this system has high thermal conductivity (2.16 W/m°K), a low viscosity (2,000 cps), and has a long pot life with a low exothermic reaction, making it ideal for large castings. Typical applications for the 50-3150FR include potting and encapsulating power supplies, transformers, electric motors, capacitors, batteries, coils, insulators, sensors, devices for intrinsic safety, etc. To download a technical bulletin, click here.
