About Sealant Flexibility

Self-Leveling Silicone Sealants
Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish. 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.

Self-Leveling Silicone Sealants with Material Certification
These sealants include a material certificate with traceable lot number, test report, and product shelf life. Thinner than non-sagging sealants, these sealants flow easily into cracks and have a smooth finish. They’re also known as RTV (room-temperature vulcanizing).
Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation.
