    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.

    HVAC Sealants

    Form flexible water-resistant seals on metal, plastic, and rubber joints in heating, ventilation, air conditioning, and refrigeration applications. These sealants are 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.

    Also known as neutral cure, this sealant won't discolor copper, brass, and concrete. It is a structural sealant that combines the mechanical strength of an adhesive with excellent sealing properties and high flexibility. 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).
    Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement a sealant can sustain. This sealant is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
