MOLYKOTE® 5 Compound
Fulfilled By ChemPoint
SKU
0131754
MOLYKOTE® 5 Compound is a high dielectric, non-conductive silicone compound designed to protect high current switches, insulators, and bushings from moisture-driven arcing and flashover. It is an NLGI Grade 3 grease-like paste that stays in place and provides water-repellent, long-lasting electrical protection.

Overview
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.
Features & Benefits
- Virtually inert and non-volatile performance
- Robust temperature operating range (-65°F to 450°F)
- Excellent oxidative & moisture resistance
- Easy to apply without stringing
- Reduced arcing or electrical flashover
- Non-conductive
- Excellent water-repellent performance
- High quality silicone (dimethyl and phenylmethyl-based fluids)
- Very effective on metal-to-metal surfaces
Problems Solved
Arcing and flashover risk on insulators and bushings in wet or contaminated service
Electrical compound that does not hold up long-term, driving repeat reapplication and recurring reliability concerns
Compounds that are difficult to apply cleanly (stringing, poor stay-in-place behavior)
Applications
MOLYKOTE® 5 Compound is a versatile electrical protective coating and lubricant that can be used for a variety of equipment types and applications, including:
High current insulators and bushings
High-voltage equipment and systems
Insulator threads and bolts
Contacts and band-tightening fasteners or screws (hardware adjacent to electrical interfaces)
Jacketed control cables
Static and dynamic O-ring seals
Plastic, metal, and rubber surfaces where water-repellent, non-conductive protection is needed
