    Low-Outgassing Silicone Rubber Sealants

    Image of Product. Front orientation. Sealants. Low-Outgassing Silicone Rubber Sealants, Cartridge.

    Cartridge

    Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Made of silicone rubber, they’re RTV (room-temperature vulcanizing), so they’ll fully harden at room temperature.
    Elongation indicates flexibility—the higher the value is, the more a sealant can stretch.

    Epoxy Potting Compounds for Harsh Environments

    Image of Product. Front orientation. Potting Compounds. Epoxy Potting Compounds for Harsh Environments.
    Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.
    They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

    Optically Clear All-Weather Application Sealants

    Image of Product. Front orientation. Sealants. Optically Clear All-Weather Application Sealants.
    Clear enough to read through, this UV-resistant sealant allows optimal light transmission for use with solar cells and fiber optics. Apply it in cold temperatures, on wet surfaces, and even through running water. The sealant is non-sagging, so it won't drip from vertical and overhead surfaces. It cannot be sold to the regions listed due to 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.

    Self-Fusing Rubber Sealing Tape

    Image of Product. Front orientation. Repair and Duct Tape. Self-Fusing, Sealing.
    Bonds to itself for a permanent, watertight seal. This tape has no adhesive, so it won't dry out and crack, which can cause standard tape to fail over time. The rubber backing molds to irregular surfaces and withstands demanding conditions, making this tape a good choice for patching and sealing anything from roofs to pipes.
    Silicone Rubber—Your best choice to repair pipe, this tape withstands harsh chemicals and the widest temperature range. However, it breaks down when exposed to oil, grease, or fuel.

    Submersible Sealants

    These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.
    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.

    UV-Resistant Glass Sealants

    These sealants don't degrade in sunlight. Also known as glazing compounds, use these sealants to install glass in framing. 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).
    Elongation and joint compression/expansion tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance.

    High-Strength Self-Leveling Concrete Joint Sealants

    Image of Product. Front orientation. Sealants. High-Strength Self-Leveling Concrete Joint Sealants.
    Seal concrete joints in high-traffic locations—these sealants stand up to heavy wear and tear, such as steel wheel traffic. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
    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. For high-wear applications, choose a harder sealant for the most abrasion resistance.
