ANCOR–Dielectric Silicone Compound
Dielectric Silicone Compound
Use this silicone grease to prevent water intrusion and keep corrosion under control.
Dielectric (non-conducting) silicone greases are used to coat and seal around electrical connections—preventing the ingress of moisture, thereby helping to prevent corrosion and failure of the connection.
Great insulator: The fact that the grease is an electrical insulator is not an issue, as silicone grease has a low viscosity and is squeezed out of the actual metal-to-metal contact area when the connection is tightened—leaving the remaining grease as an insulating, gap-filling, coating around the contact point(s). However, silicone grease alone is not an acceptable way to “insulate” an electrical connection. This is typically accomplished by a rubber, vinyl, nylon, heatshrink, etc. cover, sleeve or boot.
Works with rubber parts: Silicone grease is excellent for lubricating and preserving rubber components—like O-rings and spark plug wire boots. Unlike hydrocarbon-based greases, silicone grease won’t cause the rubber to swell or soften. Prevents the common problem of spark plug boots fusing to the spark plug insulator.
Not for use where electric arcs can happen: Electrical contact arcs have the ability to alter the composition of greases. These sparking arcs can convert silicone grease to silicone carbide, which is highly abrasive. As a result, silicone grease should be avoided in applications where contacts are "hot switched" with any chance of arcing, as the resulting silicone carbide will wear down the contact points.
