MASTER BOND EP39MAOHT two component, thermally conductive, electrically insulative epoxy can be used for bonding, sealing, coating, potting and encapsulation. The mix ratio is a forgiving one to one by weight, and after mixing, the epoxy flows smoothly. Upon mixing, this lower viscosity system has a relatively long working life. Product will cure at room temperature in 3-5 days. An alternative is to heat cure for 3-4 hours at 150-200∞F. An optimum cure schedule would be overnight at room temperature followed by 3-5 hours at 150-200∞F. Product has very low shrinkage and good dimensional stability upon curing.
