3M™ Scotchcast™ Electrical Resin 281 can be cured at low temperatures, but the optimum properties are obtained with the higher temperature cure schedules. This resin should be used instead of 3M Scotchcast Electrical Resin 241 where greater mechanical strength, higher tensile strength, better thermal shock ad higher thermal conductivity are required. - 3M™ Scotchcast™ electrical resin 281 is characterized by high-temperature and electrical stability, and excellent retention of flexibility, even after prolonged heat aging.
