About Sealant Flexibility

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

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. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Optically Clear Sealants

Clear enough to read through, these UV-resistant sealants allow optimal light transmission for use with solar cells and fiber optics. 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.

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.

Caulk

Caulk is non-sagging, so it 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 a sealant can sustain. Caulk is best suited to joints between similar materials that aren't exposed to 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. For high-wear applications, choose a harder sealant for the most abrasion resistance.

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, these sealants are RTV (room-temperature vulcanizing).
