About Sealant Flexibility
More
Silicone Sealants

Made from silicone, these sealants are RTV (room-temperature vulcanizing). 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. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.
