If you are seeing intermittent electrical issues, tracking on insulators, or recurring maintenance tied to wet or contaminated environments, MOLYKOTE^® 5 Compound is built for that exact problem set. It is a silicone-based grease-like paste engineered for long-term protection of high current electrical switches and insulators, with non-conductive and water-resistance performance intended to extend service life versus conventional compound approaches.

Where it fits best is when you need a high dielectric switch insulating compound or grease that:

• Repels water and resists moisture intrusion


• Helps reduce arcing and flashover frequency on insulators and bushings


• Stays put on threads, bolts, and contact-adjacent hardware without being messy or stringy

Key selection proof points, for engineers and maintenance teams:

• Temperature operating range: -65°F to 450°F (-54°C to 232°C)


• Dielectric strength (50 mil gap): 545 V/mil


• Arc resistance (ASTM D495): 101 seconds


• NLGI Grade 3, silica thickened, translucent light gray

If you are unsure whether you need an insulating compound, a contact lubricant, or an anti-seize for fasteners in the same assembly, send us the component and operating conditions. We will confirm the best-fit MOLYKOTE^® grade and packaging for your maintenance process.
