Material Notes:
Master Bond Polymer System EP39MHT is a low viscosity, two component, epoxy resin system for high performance potting, encapsulation, sealing and bonding. It cures readily at ambient temperatures to an exceptionally tough and thermally stable thermosetting polymer featuring outstanding electrical insulation properties and remarkably high resistance to thermal shocks and mechanical vibration. EP39MHT also features inertness upon exposure to water and a wide range of chemicals plus capability
for sustained service at temperatures up to as high as 450°F.
