Electrical insulating compound provides a moisture-proof seal for aircraft, automotive and marine ignition systems and spark plug connections.
Dow Corning 4 electrical insulating compound provides a moisture-proof seal for aircraft, automotive and marine ignition systems and spark plug connections.
A dimethyl silicone compound, 4 electrical insulating compound lubricates and forms a moisture-proof, electrically insulating seal for spark plug connections, electrical connections, and electrical assemblies and terminals.
Also, it can seal and lubricates cable connectors, battery terminals, rubber door seals, and rubber and plastic O-rings, and can be used as an assembly lubricant in metal-on-plastic and metal-on-rubber combinations.
4 electrical insulating compound is resistant to wide range of organic and inorganic chemicals, as well as mineral oils, vegetable oils, air, dilute acids, alkalines, and most aqueous solutions.
Odourless, practically nonvolatile, nontoxic and nonmelting, the compound has excellent release and sealing properties and shows little tendency to dry out in service.
It maintains serviceable consistency from -57 to +204C.
