About Sealant Flexibility
More
Puncture-Resistant Sealants
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.

Structural Sealants
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.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

All-Weather Application Structural Sealants
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.

Structural Noncorrosive Silicone Sealants
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, 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.

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.

High-Strength Concrete Joint Sealants
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.
