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).

Noncorrosive Silicone Sealants with Material Certification
This sealant includes a material certificate with traceable lot number, test report, and product shelf life. Also known as neutral-cure, this sealant won't discolor copper, brass, and concrete. It’s non-sagging, so it won't drip from vertical and overhead surfaces. Made from silicone, this sealant is RTV (room-temperature vulcanizing). It cannot be sold to California because it exceeds 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.
