Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. They work especially well on metals.

To allow time to adjust and position parts, these epoxies remain workable for at least 90 minutes.

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

These machinable epoxies are mixed with steel, but won’t rust, so they can be used to repair cracks and threaded holes.

Toughened adhesives are blended with rubber particles for better impact resistance than standard acrylics. They form resilient bonds.

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

Apply these adhesives on two surfaces, air dry, and then bring together to bond.

Temporarily stabilize objects on flat surfaces with this clear, reusable adhesive.

Bond glass and stone to drywall, treated lumber, and subfloors.

Install vinyl and rubber treads on stairs with this adhesive.

Install foam insulation, drywall, and paneling with these adhesives.

Permanently set threaded rods, studs, and rebar in concrete.

When concrete is saturated or submerged in water, use these adhesives to form strong bonds.

These adhesives maintain their strength at temperatures up to 250° F.

The polyurethane glue in these cartridges has nearly twice the shear strength of other hot-melt adhesives.

Made from silicone, these sealants are RTV (room-temperature vulcanizing).

Resistant to mold and mildew, these sealants are well suited to high-humidity environments.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

A combination of hardness and surface tension makes these sealants resistant to punctures, cuts, and abrasion.

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

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.

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

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

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

The textured finish matches concrete surfaces.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

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