Product Description
Advantages of 3M™ Scotchcast™ Electrical Resin 281
- 65 Shore D hardness
- 22 minute gel time at 121°C (250 °F)
- Useful for coating coils, transformers, motors, modules, electrical and electronic components
- Temperature rated Class F (155˚C)
- Elongates 45% longer than its original size for easy insulation or wrapping
- Chemical and moisture resistant
3M™ Scotchcast™ Electrical Resin 281 is a 2 part, oven curing, liquid resin that is used for electronic and electrical applications requiring the highest level of protection. This filled epoxy based resin has a low viscosity and impregnating property, making it easy to infuse on most surfaces. It is useful for applications that include filling, patching, insulating and more.
3M™ Scotchcast™ Electrical Resin 281 has a low gel point rating to ensure a quick curing process when kept in warm environments. The high tensile strength of the resin exhibits a semi flexible and good adhesion property after curing. 3M™ Scotchcast™ Electrical Resin 281 is ideal for applications that need excellent thermal shock and mechanical shock resistance. Its high dielectric strength offers excellent electrical insulating property to the resin. 3M™ Scotchcast™ Electrical Resin 281 has a high flash point, helping prevent any fire hazard due to quick ignition. Since the resin exhibits a hydrolytic stability property, it minimizes quick chemical decomposition, thus providing long lasting usage. RoHS EU 2015/863 Compliant.
