LORD® EP-809 Epoxy Encapsulant Where to Buy
Product Information
LORD® EP-809 epoxy encapsulant is a two-component system designed specifically for encapsulation of high voltage, automotive ignition coils.
Shelf Life
Shelf life is six months for LORD EP-809 resin and one year for LORD EP-809 hardener from date of manufacture when stored at 25°C in original, unopened container. LORD EP-809 resin must be periodically rotated within its container to maintain maximum shelf life. Settling will occur if not mixed.
LORD 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.
