Mix these two-part epoxy surface fillers to create a strong repair in wet environments or underwater.

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.

A combination of hardness and surface tension makes these sealants resistant to punctures, cuts, and abrasion.

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

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.

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.
