U.S. Air Force Validates ENVELOP Performance

EAGAN, Minn. (April 23, 2009) - The U.S. Air Force recently released a report detailing results of a yearlong study that independently validates the superior performance of ENVELOP Protective Covers in preventing corrosion for Aerospace Ground Equipment (AGE). The intent was to study the effects of storing vital equipment in temporary shelters, and included an analysis of both traditional vinyl covers and ENVELOP covers.

AGE units in the study were stored unused for one year with complete instrumentation and corrosion coupons. The Air Force staff collected measurements each quarter. The data gathered demonstrated that ENVELOP technology is more than ten times as effective as vinyl covers in reducing corrosion rates, and nearly 20 times as effective as shelter alone. As a result, the Air Force is considering what equipment in their vast inventory would most benefit from the use of ENVELOP Protective Covers.

About ENVELOP® Protective Covers
Envelop Protective Covers are the next generation of environmental and operational covers, replacing ineffective vinyl tarps and corrosion-inhibiting chemicals that contaminate the environment. Envelop covers were originally developed to protect military weapons and other assets from water, salt, humidity, sand and other sources of environmental degradation. Validated in the Navy's ocean-going environment, Envelop covers have proven to dramatically reduce maintenance time for military assets, and they are the only soft covers approved by the U.S. Navy for topside weapons and equipment. More than 14,000 Envelop covers are now used by the U.S. Navy, U.S. Army, U.S. Marine Corps, U.S. Coast Guard, and allied navies. They are also available for consumer and industrial applications such as oil and gas machinery, commercial shipping, amusement parks, airplanes, gun cases and cruise ships. Shield Technologies Corporation is headquartered in Chicago, Ill., with operations in the Twin Cities suburb of Eagan, Minn.
