Electrical Joint Compound EJC compound is recommended for providing effi cient and trouble free service on aluminum to aluminum and aluminum to copper connections. Application Terminal to dead end connections for applications under 93º C (200º F). Flat to flat surfaces such as bus to bus, aluminum to aluminum and aluminum to copper.
Electrical Joint Compound – Features EJC compound : Paste with and without electrical fillers. This removes oxides and prevents corrosion and help to make joint stress free. Unlimited application life and compatible with AL to AL and AL to CU dissimilar metals. Lowest Electrical Resistance on Flat Surfaces No. 2 EJC has the lowest electrical resistance on fl-at surfaces because it is a grease type. Medium that dissolves the oxide on connectors. The nature of the oxide removal is not harmful. No. 2 EJC creates a light surface etch with no deep, localized attack. It only attacks the oxide.
