About Sealant Flexibility
More
Structural Submersible Sealants
The strongest submersible sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light. Sealants are non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.
Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.

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.
