These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. 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 indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation.

Sealants cannot be sold to the listed areas due to local regulatory limits on VOC (volatile organic compounds).

These sealants include a material certificate with traceable lot number, test report, and product shelf life. They are structural sealants that combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, these sealants are RTV (room-temperature vulcanizing). They cannot be sold to California due to local regulatory limits on VOC (volatile organic compounds).

Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation.

The strongest submersible sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light. Sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.

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.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Elongation and joint expansion/compression tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint expansion/compression tolerance. 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.

When Sika Sikaflex Polyurethane requires a primer, for best results use Primer 260 on metal and Primer 449 on plastic and rubber.

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.

Repair equipment and vehicle windows with these sealants that are rated to withstand impact within three hours of application. They’re non-sagging, so they won't drip from vertical and overhead surfaces. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation. They’re crash tested and meet Federal Motor Vehicle Safety Standard 212 for windshield mounting.

Elongation indicates flexibility—the higher the value is, the more joint movement a sealant can sustain.

A primer is required. For best results use P591 for composites, glass, and fiberglass and P592 for aluminum, steel, and stainless steel.

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.

Urethane adhesives are the most flexible, so they bond dissimilar materials and damp vibration.

The size listed is the combined total of the two parts. Use 1.64 fl. oz. and 1.69 fl. oz. cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives. Dispense adhesives in 10.1 fl. oz. cartridges with a standard caulk gun.

DP604NS and DP605NS stay flexible at low temperatures.

U-05FL, U-09FL, and U-09LV won't yellow.

5570 is also known as silane modified polymer.

292 resists moisture and does not require mixing.

With high shear strength and peel strength, these form the strongest bonds of our urethane adhesives. Urethanes are the most flexible adhesives, so they bond dissimilar materials and damp vibration.

The size listed is the combined total of the two parts. Use cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.
