Frequent question: Is silicone spray good for electric motors?

DO NOT USE SILICONE SPRAY ON ELECTRICAL CONNECTIONS, SWITCHES, RELAYS, ETC. There have been numerous reports that silicone spray can cause contact problems in switches, noted in multiple posts regarding automotive problems.

What is the best lubricant for an electric motor?

The grease consistency preferred for electric motors is normally NLGI 2 or 3, with a base oil viscosity of 100-150 cSt @ 40°C. Other characteristics to look for include good channeling characteristics, low oil bleed, oxidation resistance, anti-wear additives, and mechanical stability.

Will silicone lubricant damage electronics?

The silicone sprays all contain various things in them that could damage the plastics or conduct electricity which case you have an issue if it gets into connections and plugs. Best idea don’t spray stuff on it to start with and keep it clean no direct water hosing etc.

Is silicone lube electrically conductive?

Dielectric grease does not conduct electricity and stays pliable (it does not cure), while silicone grease does not conduct electricity either but cures to a hard form.

Is silicone spray conductive?

Silicone spray can be conductive and non conductive from what i understand, depending on the specific product. Either it is the conductive property, or the lubrication property. Either way – when I started using it on all my heli belts my static problems went away.

Can I spray wd40 into an electric motor?

Yes, it can as WD 40 has oil base which can make winding insulation more weaker and can damage your motor. Also, WD 40 is not recommended to be used over electrical contacts.

When should you not use silicone spray?

Because it is so slippery and persistent, avoid using silicone spray under the following conditions:

  2. On any surface upon which you walk, sit, or lay.

What can I spray on electrical connections to prevent corrosion?

Close the connection, then spray the area with CRC Marine Corrosion Inhibitor (, this is a light spray that dries to a waxy film that will displace water and prevent corrosion. The dielectric grease or anti-seize should last for years, but I’d touch up the CRC spray a few times a year.

Can you use silicone to waterproof electrical connections?

With silicone sealant, waterproofing your outdoor electrical cables is simple. If you want to waterproof a length of outdoor (or even indoor) electrical cable, silicone sealant is the best protectant to use. … Silicone sealant can be found in any hardware or home improvement store.

Where should you not use silicone grease?

Because of their high viscosity index and low surface energy, silicone greases do not create a robust hydrodynamic film to separate components and prevent wear. As a result, Nye does not recommend silicone greases for most high load applications, like metal-on-metal gearing.

What is the best grease for electrical connections?

Dielectric grease is often used to seal the connection between spark plugs and spark plug wires. Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion.

Is silicone grease good for metal?

Silicone lubricants make surfaces ultra-slippery while repelling water. They’re safe to use on rubber, plastic, wood and metal.
