    Silicone Rubber Sealants

    Made from silicone rubber, these sealants are RTV (room-temperature vulcanizing). 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. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

    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).

    Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish. 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 sealants include a material certificate with traceable lot number, test report, and product shelf life. 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 indicates flexibility—the higher the value is, the more a sealant can stretch. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

    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).

    Oil- and Fuel-Resistant Sealants

    These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re thicker than most non-sagging sealants, so they can be used in vertical joints up to 1/2" wide.
    Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
    Silicone Rubber—Silicone rubber sealants have excellent ozone resistance.

    Noncorrosive Silicone Rubber Sealants with Material Certification

    Image of Product. Front orientation. Sealants. Noncorrosive Silicone Rubber Sealants with Material Certification.
    This sealant includes a material certificate with traceable lot number, test report, and product shelf life. Also known as neutral-cure, this sealant won't discolor copper, brass, and concrete. It’s non-sagging, so it won't drip from vertical and overhead surfaces. Made from silicone rubber, this sealant is RTV (room-temperature vulcanizing). It cannot be sold to California because it exceeds local regulatory limits on VOC (volatile organic compounds).
    Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. This sealant is good for use between dissimilar materials and in environments with wide temperature fluctuation.

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

    Structural Silicone Rubber Sealants with Material Certification

    Image of Product. Front orientation. Sealants. Structural Silicone Rubber Sealants with Material Certification.
    These sealants include a material certificate with traceable lot number, test report, and product shelf life. They are structural sealants that 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. Made from silicone rubber, these sealants are RTV (room-temperature vulcanizing). They cannot be sold to California due to local regulatory limits on VOC (volatile organic compounds).
    Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation.

    Optically Clear Two-Part Silicone Rubber Potting Compounds

    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.
