DuPont MOLYKOTE® 4 Electrical Insulating Compound can be used in a broad range of lubricating and sealing applications, including but not limited to the following: metal-on-plastic and metal-on-rubber surfaces, cable connectors, O-rings (polymer and elastomer), moisture-proof sealing, battery terminals, terminals requiring semi-flowable consistency, rubber seals, switches, assembly lubricant use, ignition systems, spark plug connections, and disconnection junctions. The compound's adaptability makes it suitable for maintenance operations where reliable moisture resistance and dielectric strength are paramount, such as in commercial electrical cabinets or sensitive industrial control equipment. Moreover, its stable performance across a wide temperature range ensures protection in both indoor and outdoor environments, thereby reducing the need for frequent reapplication and downtime. MOLYKOTE® 4 Compound was previously known as Dow Corning 4 or Dow Corning DC-4 silicone compound, thus procurement managers or engineers may recognize it under its former designation when reviewing historical maintenance records or equipment specifications.
