Even when used under water, these adhesives maintain their strength.

Assortments include eight different epoxies in 0.1-oz. packets to handle a variety of small jobs.

These sealants are marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

Clear enough to read through, this UV-resistant sealant allows optimal light transmission for use with solar cells and fiber optics.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Waterproof and strong, these surface fillers remain flexible when repairing rips, tears, and holes in neoprene rubber. They're often used on wetsuits.

These coatings provide chemical, corrosion, and impact resistance on grit-blasted concrete and primed steel in immersion, underground, and waste-water treatment applications.

Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in 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 and underwater lighting, as well as other underwater electronics from corrosion and chemicals.

Repair rips, split seams, and detached soles to stop leaks in shoes, boots, and waders.
