    Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing).
    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.

    These coatings are formulated for use in sensitive applications such as manufacturing semiconductors. Thinner than potting compounds, they flow easily into small spaces between electrical components. The coatings begin to harden when exposed to UV light. Use them to secure and insulate hardware on printed circuit boards. A gun (sold separately) is required to dispense them.

    Ready-to-Use Silicone Rubber Potting Compounds

    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.

    Light-Activated Silicone Rubber Potting Compounds

    Image of Product. Front orientation. Potting Compounds. Light-Activated Silicone Rubber Potting Compounds.
    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.

    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.
    Thin Liquid—Liquid compounds harden around your component to form a strong, durable, and permanent layer of protection.
