About Sealant Flexibility

Noncorrosive Silicone Sealants


Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete. 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. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.
Sealants that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

Sealants

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 All-Weather Application Sealants

Clear enough to read through, this UV-resistant sealant allows optimal light transmission for use with solar cells and fiber optics. Apply it in cold temperatures, on wet surfaces, and even through running water. The sealant is non-sagging, so it won't drip from vertical and overhead surfaces. It cannot be sold to the regions listed due to local regulatory limits on VOC (volatile organic compounds).
Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. This sealant is good for use between dissimilar materials and in environments with wide temperature fluctuation.

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.

Self-Leveling Oil- and Fuel-Resistant Sealants


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.
Sealants that cannot be sold to California exceed local regulatory limits on VOC (volatile organic compounds).

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).
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.

Impact-Resistant Structural Glass Sealants


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.
