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, 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.

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.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water. They are structural sealants that combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. 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 good for use between dissimilar materials and in environments with wide temperature fluctuation.

Impervious to the swelling effects of oils, fuels, and solvents, use this high-strength silicone sealant to assemble and repair fuel systems and tanks. Silicone 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.

Seal concrete joints in high-traffic areas—these sealants stand up to heavy wear and tear, such as steel wheel traffic. They're non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, 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. 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.

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.

Silicone sealant is RTV (room-temperature vulcanizing).

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.

Prepare joints and surfaces to ensure proper sealant adhesion.

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, 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.

Keep out the elements by sealing roof joints. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces. They are good for use in environments with wide temperature fluctuation.

Sealants that cannot be sold to the listed areas are restricted due to product regulations.

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, 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.
