How the Envelop Covers System Works

ENVELOP PROTECTIVE COVERS ARE CUSTOM DESIGNED
TO FIT WEAPONS AND ASSETS

We have designed over 175 unique specific covers because we understand that optimum performance and corrosion protection is directly related to the proper fit for the weapon or asset being protected. The potential cost of corrosion and environmental degradation is much too high to compromise on a "One Size Fits All" approach.

An Envelop Protective Cover is a composite structure of 4 layers that work together synergistically to protect critical assets from severe damage due to corrosion, drastically reducing maintenance requirements and increasing useful life expectancy.

This multi-layer cover protects metal surfaces by drawing the moisture out from underneath the cover and protecting the metal surfaces with EDC's (Electrolyte Displacement Compounds).

Corrosion Preventative Covering Construction

Outer Shell
Tough flexible waterproof fabric, permeable only to water vapor, allowing moisture to evaporate from beneath the covering; traps corrosion inhibitors.
Inner Wicking Layer
The inner most layer that contacts the metal surface. Hydrophobic fabric forming a hydrophilic structure that quickly wicks any water away from the metal surface.
Absorbent Inner Matrix
A super absorbent material that stores water and will only release it back to the environment when humidity is less than 100%; can also slightly depress the humidity beneath the cover, thus preventing condensation.
Corrosion Inhibiting Layer
A layer of corrosion inhibitors that will condition the micro-environment beneath the cover to reduce corrosion on the metal surface.
