    Two-Part Silicone Rubber Potting Compounds

    Encase electronic assemblies in a layer of silicone rubber 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).

    Bottle

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

    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.
    Cannot Be Sold to California—Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).
