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.

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.

Press this adhesive-backed plastic tape into place for an immediate light-duty seal.

Mix a small amount of water-based paint with this caulk to match the color of your surface.

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

Impervious to the swelling effects of oil, fuel, and solvents, use these high-strength sealants to assemble and repair fuel systems and tanks.

Designed for use on ovens and kilns, these sealants form a durable, rock-hard seal after firing.

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

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

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

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

Make repairs or changes to electrical components after they’ve been potted. While most compounds are permanent, these form a gel that bonds to itself, so you can peel it off without damaging your equipment.

Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds.

Protect circuit boards and other electronics where high heat is a concern but you don’t need to transfer that heat elsewhere. These compounds are a good middle ground between standard epoxy compounds and heat-transfer compounds.

Protect circuit boards and other electronics from fire and heat.

Urethanes withstand a wide range of temperatures and are the best choice for cold-temperature applications. They have excellent flexibility, good chemical and moisture resistance, and provide good electrical insulation.
