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.

Waterproof Epoxy Structural Adhesives
Even when used under water, these adhesives maintain their strength. The most weather- and chemical-resistant structural adhesives, epoxies tend to work especially well on metals.
The size listed is the combined total of the two parts. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.
ClearWeld and Plastic Bonder can be applied to wet surfaces.
WaterWeld and 11801, as well as one-time-use packets, can be applied to wet surfaces or under water.

Epoxy Structural Adhesives for Harsh Environments
With excellent resistance to corrosive chemicals and salt water, these epoxies work in tough conditions. Epoxies are the strongest structural adhesives. Choose an adhesive that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
The size listed is the combined total of the two parts. Use cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.
E-120HP resists acetone, fuel, and oil. It bonds dissimilar materials and withstands rapid changes in temperature.
9430 bonds dissimilar materials and resists fuel and hydraulic fluid.

Epoxy Potting Compounds for Harsh Environments
Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.
They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

Urethane Potting Compounds for Harsh Environments
From shore to sea floor, these potting compounds are formulated for permanent submersion in water—even salt water. Use them to protect circuits and splices in pumps, underwater lighting, and other underwater electronics from corrosion and chemicals. Made of urethane, they withstand a wide range of temperatures, especially cold underwater conditions. They provide good electrical insulation and have excellent flexibility. Since they’re more flexible than epoxy compounds, they’re often used to protect against vibration and impact.
Mix the two parts of these compounds together and pour them over components inside a potting box or other container. If mixing causes air bubbles, put the mixture in a vacuum chamber to remove them.
