Araldite CW 5725-3/Aradur HY 5726 – Epoxy Potting Compound for Car ignition coils

Araldite CW 5725 Resin and Hardener Aradur HY 5726 are two components of epoxy potting compound for car ignition coils which would have to resist to shock and bear a lot of heat during the process of transforming the battery’s low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.
