Thermoset™ DC-812 Epoxy Encapsulant
Product Information
Thermoset DC-812 epoxy encapsulant is a two-component system designed specifically for potting high voltage, automotive ignition coils.
Shelf Life
Shelf life is six months for Thermoset DC-812 resin and one year for Thermoset DC-812 hardener from date of manufacture when stored at 25°C in original, unopened container.
Thermoset DC-812 resin must be periodically rotated within its container to prevent settling.
Features and Benefits
Low Viscosity – maintains low viscosity for complete and void-free encapsulation.
Environmentally Resistant – provides good resistance to thermal shock.
High Temperature Electrical Performance – provides excellent electrical stability at high temperature.
