About Sealant Flexibility

Submersible Sealants
These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.
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.
