Thermoset EP-830 Epoxy Encapsulant Where to Buy
LORD Thermoset EP-830 encapsulant is a heat curing, two-component epoxy formulation designed especially for use in automotive high voltage ignition coils where adhesion to segmented bobbins is critical. The combination of low viscosity, excellent high temperature electrical performance and good thermal shock resistance make this epoxy compound ideal for this application.
Shelf life of each component is six months from date of manufacture when stored in a well ventilated area at 25°C in original, unopened container.
