3M? Scotchcast? Electrical Resin 8N is a low-stress, highly moisture-resistant
compound that cures at room temperature. This epoxy resin system offers long pot life,
low viscosity, a 1:1 mix ratio (by weight), Class B (130?C) temperature rating, and is
commonly used to coat printed circuit boards, pot connectors, and impregnate
electrical and electronic components. Because of its low exotherm, Scotchcast resin 8
is also frequently specified for impregnating and encapsulating temperature sensitive
units.
? Low exotherm
? High moisture resistance
? Highly resistant to mechanical and thermal shock
? Extended pot life
