Description

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
