About Sealant Flexibility
More
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).

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.

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).
