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.

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.

This sealant includes a material certificate with traceable lot number, test report, and product shelf life.

Keep water out of single-ply PVC or TPO plastic membranes with these self-leveling sealants.

Clear enough to read through, this UV-resistant sealant allows 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.

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

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.

These sealants are marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

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.

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

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

Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments.

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.
