Supremaseal

Construction sealants provide impermeable barriers to the external environment, wind, snow, salt water and rain. The seal prevents the penetration of the environment into the watercraft, directly or indirectly.

There are many problems with the consistency of this type of barrier concerning maintenance and life of the seal, because of the expansion and contraction of the seal. Consider reversing the philosophy of the exterior penetrating to the interior: the interior passing to the exterior.

As the interior pressures are higher than the exterior pressures, SupremaSeal allows vapors to escape while holding the exterior environment out, creating a breathable seal. A hermetic seal on the exterior surface prevents infiltration of all environmental forces. A hermetic seal allows a minor absorption of moisture, when conditions permit slowly releasing the moisture through evaporation.

When SupremaSeal is compressed 80% it becomes a Total Environmental Protection barrier. It can used in a variety of other applications beyond water infiltration.
