    Nonporous Ceramic Alumina Powder

    Image of Product. Front orientation. Ceramic. Nonporous Ceramic Alumina Powder.
    Ceramic alumina withstands higher temperatures than any other ceramic and is highly chemical resistant. This powder is high purity, so it’s inert even at high temperatures. Because alumina is ultra hard, it can be used in applications that require superior strength. It is also wear resistant, making it suitable for high-wear applications. Both thermally and electrically insulating, alumina can also be used in high-temperature and high-power electrical applications. Finished products made from alumina powder are nonporous, so they will seal out air and gas. Powder is often used in casting processes. Add it to slurries to create custom parts and tools such as crucibles, cutting tools, and laboratory ware. Alumina powder also is often used as a friction material, such as in brake linings.
    Choose a particle size based on the application of your finished piece. Finer powders can be processed into finished pieces that will be harder, stronger, and more wear-resistant than those made with coarse grains. They may also have a finer finish. Parts made with coarse grain powders can be processed into pieces that are more porous and thermally shock-resistant than pieces made with finer grains. Mixing sizes can combine these properties.
    99.3% Aluminum Oxide—99.3% aluminum oxide powder is slightly more reactive than 99.5% aluminum oxide powder because it’s less pure. It’s commonly used for polishing, lapping, and buffing.
    99.5% Aluminum Oxide—99.5% aluminum oxide powder is more pure than 99.3% aluminum oxide, so it’s less reactive. It’s often used in the ceramic, glass, and foundry industries.

    Cartridge Potting Compounds

    Make repairs or changes to electrical components after they’ve been potted. While most compounds are permanent, these form a gel that bonds to itself, so you can peel it off without damaging your equipment. Often used in junction boxes, they form a water- and dust-proof seal that’s rated IP68 while also providing excellent electrical insulation. Made of silicone rubber, they withstand a wide range of temperatures and are soft and flexible enough to resist shock and vibration. However, they’re not as strong as permanent potting compounds, so they don’t resist scrapes as well as those made of epoxy and urethane. They’re also not as chemical resistant as epoxy and urethane compounds.
    These compounds won’t solidify once you open the container, so you have time to make adjustments when applying them. When removing them from your components, they mostly come off in one piece but there might be some residue left over.
    Bottle Potting Compounds—Bottle compounds are a better choice for filling up new enclosures than cartridge compounds because you can pour more in at a time. They have a compartment for each component and require mixing.
    Cartridge Potting Compounds—Cartridge compounds have a nozzle for precise application. The nozzle can also fit into junction box knockouts, so it’s easier to fill up installed enclosures than it is with bottle compounds. They come ready to use with no mixing required and no waiting time.

    No mixing required—these potting compounds come ready to apply. Use them to encase electronic assemblies for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone rubber potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They're also known as RTV (room-temperature vulcanizing) compounds because they don’t need heat or UV light to cure.

    Protect circuit boards and other electronics where high heat is a concern but you don’t need to transfer that heat elsewhere. These compounds are a good middle ground between standard epoxy compounds and heat-transfer compounds. They work at temperatures twice as high as standard epoxy compounds. However, they don't conduct heat as well as heat-transfer compounds so they're not the best choice for circuit boards that run for long periods of time. Harden these compounds at room temperature—they don’t require an oven to harden like heat-transfer compounds do.
    Since they’re an epoxy compound, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators and withstand a wide range of temperatures. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration.
    Jar and Syringe—Jar and syringe compounds are the consistency of honey once they’re mixed, so they’ll seep into the crevices of a circuit board and encapsulate intricate components. Use the syringe for precise application.
    Bottle—Bottle compounds are easier to apply in higher volumes than jar and syringe compounds. Mix them together and pour them over components inside containers, such as a potting box. If air bubbles occur after mixing, you can put the mixture in a vacuum chamber to remove them.

    Flexible Epoxy Potting Compounds

    Image of Product. Front orientation. Potting Compounds. Flexible Epoxy Potting Compounds.
    Combine the flexibility of silicone with the durability of standard epoxy—these compounds are great for protecting sensitive electronics that need to flex or expand and contract. Because they’re an epoxy, they still have excellent moisture, chemical, and abrasion resistance. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. You can also use them as an adhesive since they’re also tacky.
    They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

    Urethane Potting Compounds for Harsh Environments

    Image of Product. Front orientation. Potting Compounds. Urethane Potting Compounds for Harsh Environments.
    From shore to sea floor, these potting compounds are formulated for permanent submersion in water—even salt water. Use them to protect circuits and splices in pumps, underwater lighting, and other underwater electronics from corrosion and chemicals. Made of urethane, they withstand a wide range of temperatures, especially cold underwater conditions. They provide good electrical insulation and have excellent flexibility. Since they’re more flexible than epoxy compounds, they’re often used to protect against vibration and impact.
    Mix the two parts of these compounds together and pour them over components inside a potting box or other container. If mixing causes air bubbles, put the mixture in a vacuum chamber to remove them.

    Can

    Protect circuit boards and other electronics from fire and heat. These self-extinguishing compounds meet UL 94V-0 for flame retardance and withstand temperatures up to nearly 400° F. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration. Since they’re epoxies, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators. These compounds have the consistency of honey once they’re mixed, so they seep into crevices to encase intricate components.
    Cartridge—Cartridge compounds dispense through a mixer nozzle for precise application. Use them with a dispensing gun.
    Can—Can compounds are easier to apply in high volumes than cartridge compounds. Mix them together and pour them over components inside containers, such as a potting box. If you see air bubbles after mixing, put the mixture in a vacuum chamber to remove them.
    Cannot Be Sold to Canada—These compounds cannot be sold to Canada.
