    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).

    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).

    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.

    Form seals that resist punctures, cuts, and abrasion to withstand heavy wear and tampering. These sealants are 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. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
