    These lubricants go on wet for easy application. Once dry, they form a nonstick film that won't attract dust. Use them for general purpose lubricating in most applications.
    Pail—Dilute 1-gallon pail with water before using.
    Boron Nitride Additive—Lubricants with boron nitride resist corrosion from salt water and won’t wash off.
    Ceramic Additive—Lubricants with ceramic are often used in extreme-temperature applications, such as welding, metal processing, and glassmaking.

    Non-Bonding Heat Transfer Compounds

    Image of Product. Front orientation. Thermal Paste. Non-Bonding Heat Transfer Compounds.
    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.

    This grease is wear resistant for use in a wide range of bearing types.
    Grease lubricates most efficiently within the listed temperature range.
    Chemours—Chemours Krytox™ grease is long lasting with an indefinite shelf life.
    Krytox™ XHT-BDX—Krytox™ XHT grease can be used at extremely high temperatures.
    Boron Nitride Thickener—Grease with boron nitride thickener has excellent heat resistance and good moisture and oxidation resistance.
    2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.
    Nonmelting—Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.
    Melting Temperature—Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.
