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

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

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

Compliant with ASTM E-595, these sealants produce almost no volatile materials in a vacuum.

Meeting requirements for semiconductor, biomedical, and electronics clean rooms, these sealants won’t contaminate air and surfaces.

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

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

The strongest submersible sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

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

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

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

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

These sealants don't degrade in sunlight.

Form flexible water-resistant seals on metal, plastic, and rubber joints in heating, ventilation, air conditioning, and refrigeration applications.

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