EJC
Electrical Joint Compounds



Product Description :

TIM-Electrical Joint Compounds (EJC) is specially formulated with latest technology to prevent oxide film formation on metal surfaces and prevents corrosion. It offers superior weathering characteristics over wide temperature ranges, and provides highly conductive tight joints. Proprietary filler particles help in penetrating oxide films and act as electrical bridges between conductor strands, aid in gripping conductor, improve electrical conductivity and enhance integrity of the connection.

Surface contamination, especially surface oxide, must be expected on all conductors, these surface oxide films are insulators and must be broken down to achieve the metal-to-metal contact required for efficient electrical connections. Aluminum oxide, in particular, forms very rapidly; therefore, aluminum conductors must be thoroughly cleaned by use of an emery cloth prior to making the connection, In addition to cleaning, surface should be covered with joint compound to exclude moisture, thus preventing the oxide from reforming

EJC Compounds:

EJC 744:
Gritted electrical joint compound is recommended for all aluminum and copper compression connections. It is not recommended as lubricant on threaded fittings.

EJC 745NS:
Non-gritted Non-Silicone electrical joint compound recommended for No-Drip application for aluminum and copper connectors.


EJC 745SL:
Non-gritted Silicone electrical joint compound recommended for rigid bus connection, bolted flat-pad connection between aluminum and aluminum and copper applications.
