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

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

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

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

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

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

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

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

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

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.

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

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