    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.

    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.
    UL 94 V-0—Potting compounds that meet UL 94 V-0 have passed a test for flame retardance.

    Impervious to the swelling effects of oils, fuels, and solvents, use this high-strength silicone rubber sealant to assemble and repair fuel systems and tanks. Silicone rubber forms a tough, rubbery, UV-resistant seal that remains flexible over time. It's non-sagging, so it won't drip from vertical and overhead surfaces. Also known as RTV (room-temperature vulcanizing).
    Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. This sealant is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
