    About Sealants
    industrial info icon

    Select a sealant that can stretch, contract, and expand enough for your joints.

    Sealants

    Image of Product. Front orientation. Sealants. Sealants.
    These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.
    Elongation and joint compression/expansion tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

    These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re non-sagging, so they won't drip from vertical and overhead surfaces.
    Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance.

    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.
    UL 94 V-0—Potting compounds that meet UL 94 V-0 have passed a test for flame retardance.
    Cannot Be Sold to California—Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).
    Cannot Be Sold to Canada—Potting compounds that cannot be sold to Canada are restricted by product labeling requirements.

    Submersible Sealants

    These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.
    Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

    Image of Product. Front orientation. Sealants. Self-Leveling All-Weather Application Concrete Joint Sealants.
    Apply these sealants on wet surfaces and in cold temperatures. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
    Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain.
    Begins to Harden in 3 min.—Sealants that begin to harden in 3 minutes are ideal for sealing pavement saw cuts made when installing buried sensing wires, also known as detector loops. You can walk or drive over the seams right away because they dry tack free within minutes.
    Cannot Be Sold To—Sealants that cannot be sold to the listed areas exceed VOC (Volatile Organic Compounds) regulations.

    Urethanes are the most flexible adhesives, so they bond dissimilar materials and damp vibration.
    Some of these adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Model Number 292—Do not require mixing.
    Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
    Paste—Thicker than liquid adhesives but still spreadable—good for filling gaps and covering surfaces.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

    These compounds dry quickly when exposed to UV light allowing you to handle the potted items sooner. Made of silicone rubber, they’re softer and more flexible than epoxy or urethane compounds, so they’re better at protecting against shocks and vibration. They also withstand a wider range of temperatures, so they’re often used with electronics that heat and cool rapidly. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. However, they don’t hold up well to abrasion or chemicals. The tapered nozzle lets you apply them precisely.

    Low-Outgassing Optically Clear Two-Part Silicone Rubber Potting Compounds

    Image of Product. Front orientation. Potting Compounds. Low-Outgassing Optically Clear Two-Part Silicone Rubber Potting Compounds.
    Tested to meet ASTM E595, a standard used by NASA, these compounds produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Light passes through them easily, so they’re ideal for protecting solar cells and fiber optics. Made of silicone rubber, these compounds are softer and more flexible than epoxy and urethane compounds. That means they’re better at protecting against shocks and vibration. They also withstand a wider range of temperatures, so you can use them with electronics that heat and cool rapidly. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. However, they don’t hold up well to chemicals or scrapes. They’re also known as RTV (room-temperature vulcanizing).
    These compounds are easy to apply in high volumes. Just mix the two parts together and pour them over components inside a container, such as a potting box.

    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.

    Clear enough to read through, these UV-resistant potting compounds allow optimal light transmission for use with LEDs, solar cells, and fiber optics. 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, these silicone rubber compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have excellent electrical insulation and good moisture resistance but poor chemical and abrasion resistance. Also known as RTV (room-temperature vulcanizing).
    Cartridge—Compounds in a cartridge come with a mixer nozzle for precise application. You need a gun (sold separately) to dispense.
    Bottle—Compounds in a bottle are easy to apply in high volumes. Just mix and pour them over components inside containers, such as potting boxes.
    Thick Liquid and Thin Liquid—Liquid compounds harden around your component to form a strong, durable, and permanent layer of protection.
    Gel—Gel compounds form a soft and flexible layer of protection. You can also remove them if you need to re-access your components. They are rated IP68 once potted, so they seal out water even if submersed.

    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.
