Dow Corning DC4 Electrical Insulating Compound
Are you looking for a reliable, high-quality solution for sealing and lubricating electrical equipment? The Dow Corning DC4 Electrical Insulating Compound (now sold under the brand MOLYKOTE DC4) is the industry standard for protecting electrical connections against moisture and environmental influences.
This silica-filled, non-curing silicone compound is essential for any professional working with low to medium voltage systems.
Key Features
- Superior Water Resistance: The DC4 compound effectively repels moisture, helping to prevent short circuits and corrosion in electrical systems. This is crucial for outdoor applications or in wet environments.
- Excellent Dielectric Strength: Provides strong insulation, minimizing leakage currents and maintaining the electrical integrity of the connections.
- Wide Operating Temperature: Remains stable and functional in extreme temperatures.
- Chemically Inert: Does not cause corrosion to metals and is safe for use on most rubbers and plastics.
- Long Lifespan: Once applied, the compound offers long-lasting protection and reduces the need for frequent maintenance.
Applications
The Dow Corning DC4 compound is widely used for:
- Sealing underground and above-ground electrical connections.
- Lubricating cable connections and disconnect switches.
- Protecting ignition systems, spark plugs, and terminals in vehicles.
- Sealing instrumentation housings and electrical access points.
Specifications (In the Text)
The Dow Corning DC4 Electrical Insulating Compound is a silicone grease with an excellent temperature range. The compound is optimized for an operating temperature range of approximately -55 degrees Celsius to +200 degrees Celsius. The product has a dielectric strength of at least 500 volts per mil (approximately 20 kilovolts per millimeter), confirming its high insulation value. The specific gravity of the compound is typically around 1.00 g/cm³. It is a non-melting, non-curing paste with a consistency typically described as a thick, smooth paste (similar to an NLGI class 2 or 3). The product is available in a standard tube or can of various sizes (for example, 150 gram tube or 3.6 kilogram can).
