These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

With chemical and metal additives that are picked up by X-ray machines and metal detectors, these sealants are designed to help you comply with Hazard Analysis and Critical Control Point (HACCP) programs in food-processing facilities.

Made from silicone, these sealants are RTV (room-temperature vulcanizing). They combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

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.

Bond most materials without the strong odor of other epoxy adhesives.

With excellent resistance to corrosive chemicals and salt water, these epoxies work in tough conditions.

Urethane adhesives are the most flexible, so they bond dissimilar materials and damp vibration.

Fasten hard-to-bond plastics, such as polypropylene and polyethylene, with these adhesives.

No need to mix these acrylics—apply adhesive to one surface and activator to the other, then bring surfaces together to bond.

For easy positioning, these adhesives begin to harden only when exposed to light.

Mix these two-part surface fillers together to repair leaks and cracks as well as to rebuild rough spots in metal.

Use these two-part fillers to rebuild cracked or worn plastic surfaces.

Also known as brushable ceramic, these coatings create a hard, low-friction surface. They're often used on liquid processing equipment to protect worn areas and reduce turbulence.

Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments.

The strongest of the potting compounds, epoxies are rigid and wear resistant. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.

Thinner than potting compounds, these rigid and wear-resistant coatings flow easily into small spaces between electrical components. Use them to secure and insulate hardware on printed circuit boards.
