About Lubricants

About Grease

Copper allows these lubricants to conduct electricity, while graphite gives them good chemical and corrosion resistance. Also known as thread lubricants, antiseize lubricants prevent threaded fasteners and close-fitting parts from locking together due to corrosion, contamination, or heat.

Loctite® C5-A Copper-Based Anti-Seize lubricants can be used with salt water and petroleum-based chemicals. LB 8065 comes as a stick for no-mess application.

Lubricants that meet MIL-A-907 and MIL-PRF-907 have been tested to prevent corrosion of copper and for antiseize properties when used with steel nuts and studs.

Dielectric strength measures the maximum voltage a lubricant can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.

Electrical resistivity is a measure of how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

Electrical-Insulating Grease

Also known as dielectric grease, use insulating grease to lubricate and protect electrical systems. It resists water and corrosion. This grease can be used on most rubber and plastic.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. NLGI 2 is about the consistency of peanut butter. NLGI 3 is about the consistency of vegetable shortening.

Dielectric strength measures the maximum voltage a grease can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.

Grease lubricates most efficiently below the maximum temperature. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.

Molykote 5 Compound is for use on insulators, bushings, and high-current switches.

Food Industry Electrical-Insulating Grease

Use this grease in areas where there is the possibility of contact with food. Also known as dielectric grease, it lubricates and protects electrical systems. It resists water and corrosion. This grease can be used on most rubber and plastic.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. Dielectric strength measures the maximum voltage a grease can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.

Grease that is NSF Registered H1 and grease that meets FDA Compliant 21 CFR 178.3570 are rated for incidental contact with food. Grease that meets NSF/ANSI 51 and FDA Compliant 21 CFR 175.300 are rated for direct contact with food. Grease that meets NSF/ANSI 61 is certified for use with components that come into contact with drinking water.

Grease lubricates most efficiently below the maximum temperature. DuPont Molykote 4 Electrical Insulating Compound also acts as a moisture barrier.

Electrically and Thermally Conductive Grease

A high silver content gives this grease excellent conductivity for applications where electricity and heat transfer are required. It is suitable for ESD (electrostatic discharge) and EMI (electromagnetic interference) shielding applications. Product regulations restrict sales to the listed jurisdictions/areas.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.

Electrical resistivity is a measure of how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.

Grease lubricates most efficiently within the listed temperature range. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

Grease for Electrical Contacts

Lubricate, clean, deoxidize, and prevent corrosion on electrical contacts to improve their performance.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.

Grease with only deoxidizer provides the best lubrication and is for use on clean surfaces.

Grease lubricates most efficiently within the listed temperature range. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

Non-Bonding Heat Transfer Compounds

Heat Transfer Compound

Also known as thermal paste, these boron-nitride compounds increase heat transfer between parts while preventing them from sticking. Unlike antiseize compounds, they don't conduct electricity, so you won't risk shorting out sensitive electronics. They're often used on thermocouple probes to improve accuracy. You can also use them in 3D printer heating blocks and other high-temperature areas to keep parts from fusing together.
