Thermoset EP-809 Epoxy Encapsulant Where to Buy
LORD Thermoset EP-809 epoxy encapsulant is a two-component system designed specifically for encapsulation of high voltage, automotive ignition coils.
Shelf life is six months for Thermoset EP-809 resin and one year for Thermoset EP-809 hardener from date of manufacture when stored at 25°C in original, unopened container. Thermoset EP-809 resin must be periodically rotated within its container to maintain maximum shelf life. Settling will occur if not mixed.
Thermoset EP-809 hardener may crystallize during shipment or storage. If crystals appear, gently warm hardener at 50-65°C to melt crystals before mixing with resin.
Features and Benefits
Low Viscosity – maintains low viscosity for complete and void-free encapsulation.
Environmentally Resistant – provides excellent resistance to thermal shock.
