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.

Silicone Sealants with Material Certification
These sealants include a material certificate with traceable lot number, test report, and product shelf life. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).
Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
