A dimethyl silicone compound, 4 Electrical Insulating Compound lubricates and forms a moisture-proof, electrically-insulating seal for electrical connections, electrical assemblies and terminals. Also, it can seal and lubricate cable connectors, battery terminals and rubber and plastic O-rings. It 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. Odorless, practically nonvolatile, nontoxic and non-melting, the compound has excellent release and sealing properties and shows little tendency to dry out in service. It maintains serviceable consistency from -70° to 400° (-57° to 204°C).
