Details
Highlights
- 2:3 mix ratio
- Gel time of 20 minutes
- Cures at oven temperature
- Exhibits good electrical properties
- Good thermal shock resistance
- Chemical and moisture resistant
3M™ Scotchcast™ Electrical Resin 280 is an unfilled, semi-flexible epoxy. It exhibits high-temperature stability, superior electrical properties, and thermal shock resistance.
3M™ Scotchcast™ Electrical Resin 280 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. It 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. It 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 RoHS EU 2015/863 Compliant.
Suggested applications
- Indicated for impregnating and encapsulating temperature sensitive units
