High Performance Epoxy Resin System

Master Bond presents the EP121AO, a two component, high performance epoxy resin system featuring top notch temperature resistance, impressive thermal conductivity, superior electrical insulation properties and outstanding dimensional stability. It has an easy to use 100:80 mix ratio by weight. After mixing EP121AO is a lower viscosity epoxy with wonderful flow properties for coating, sealing, potting and encapsulation applications. Adhesion to metals, composites, glass, ceramics and many rubbers and plastics is first rate. As mentioned previously its salient features include prominent thermal conductivity, reliable electrical insulation properties and striking dimensional stability. The service temperature range is -60°F to +500°F.

EP121AO features an extremely long open time of 1-2 days but requires oven curing. A typical cure schedule is 2-3 hours at 250°F followed by 5-8 hours at 300°F with a 2 hour or longer post cure at 350°F, although, a number of variations are possible. It also should be noted that EP121AO has exceptionally low exotherm upon curing and is an excellent fit for larger sized encapsulation or potting applications. EP121AO is most commonly used in electronics as a potting and encapsulation material when the combination of properties mentioned above is desirable.
