    Epoxy Potting Compounds for Harsh Environments

    Image of Product. Front orientation. Potting Compounds. Epoxy Potting Compounds for Harsh Environments.
    Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.
    They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

    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).

    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.
    Cannot Be Sold to Canada—Some compounds cannot be sold to Canada due to product labeling requirements.

    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.

    To simultaneously mix and dispense two-part adhesives, attach these mixer nozzles to a dual cartridge. Mixing elements help combine the two parts of an adhesive as it flows through the nozzle. A short nozzle with many mixing elements combines adhesive while minimizing the adhesive left in the nozzle after dispensing. Choose a nozzle that matches the connection type, size, and mix ratio of your adhesive cartridge.

    High humidity, harsh chemicals, water submersions, and salt are no match for these electronic coatings. They also resist UV light, so they’ll work outdoors. Use them on circuit boards, sensors, and LED drivers in heavy machinery. They’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely.
    Epoxy—Epoxy coatings resist impact and wear better than PVDF coatings, and they work in higher temperatures. You can also use them as an adhesive. For controlled pouring, they’re thickened with silicate. These coatings are autoclavable, and they’ll even cure underwater. Dispense them with a mixer nozzle and a gun (each sold separately).

    Coat electronics for durability in tough conditions while blocking EMI/RFI signals. Made of epoxy mixed with silver-coated copper, these coatings are stronger than acrylic plastic EMI/RFI coatings. They are rigid enough to withstand the wear of access panels and industrial cabinets. You can also use them in engine compartments because they resist damage from high temperatures and chemicals. Also known as conductive paint, they shield your parts from interference that could cause circuit malfunction and data loss. Mix the two parts of these compounds together and paint them on components.

    Handle potted items within minutes—these potting compounds dry quickly when exposed to UV light. For added strength and durability, cure them with heat. Since they’re epoxy, 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. You need a mixer nozzle (not included) and a gun and plunger (both sold separately) to dispense. The nozzle lets you apply these compounds precisely.
    For maximum effectiveness, these compounds need to be heat cured after they’re cured with UV light. Overall dry time includes heat curing at 149° F.

    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.

    Epoxy

    Dispense ready-to-use conductive liquid to fill pits and small gaps on circuit board components. These pens are also used to sketch and repair conductive pathways.
    Carbon Filled—Carbon acrylic plastic pens should be used where only a small amount of conductivity is needed, such as circuit boards in keyboards. Their high surface resistivity only allows a small current to pass.
    Nickel Filled—Nickel acrylic plastic pens are best for general purpose repairs, such as bridges and traces in printed circuit boards. They have a medium surface resistivity, so they're a good balance between carbon acrylic and silver epoxy pens.
    Silver Filled—Silver epoxy pens are the most versatile—use them for any type of repair as well as for repairs that require excellent conductivity, such as connecting through holes on circuit boards without adding jumpers, wiring, or solder. Since they have the lowest surface resistivity, they allow the most current to pass.
