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.
Sika Sikaflex sealants meet NSF/ANSI 61 safety standards for use with drinking water.
Silicone sealant is FDA compliant for direct contact with food. It will not harm fish, so it's safe for use in aquariums. It's also known as 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.

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.

All-Weather Application Sealants
Apply these sealants on wet surfaces and in cold temperatures. They’re non-sagging, so they won't drip from vertical and overhead surfaces.
Sealants with 1,000% elongation can be applied through running water.
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 the regions listed are restricted by local chemical regulations, including limits on VOC (volatile organic compounds).
