    Heat-Transfer Epoxy Potting Compounds

    Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.

    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).

    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.

    Cartridge

    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, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. All require a mixer nozzle and gun to dispense.

    Take your time positioning parts that require precise alignment, such as optical instruments. Instead of gripping immediately, these adhesives only harden when you expose them to a compatible light source.
    Syringe—Apply with a dispensing gun.
    Thick Liquid—Fill larger gaps than thin-liquid adhesives, so they're better for bonding slightly misaligned or uneven surfaces.
    ISO 10993—Comply with biocompatibility standards for medical-grade applications.

    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 UK U-05FL—Will not yellow.
    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.

    Optically Clear Epoxy Structural Adhesives

    Cartridge

    For invisible bond lines, these adhesives dry clear. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an epoxy that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
    These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.
