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

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.

Clear enough to read through, these UV-resistant sealants allow optimal light transmission for use with solar cells and fiber optics.

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

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.

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.

Fix roof leaks in cold and wet conditions. These sealants can even be applied underwater.
