Evaluating Cortec VpCI-126 Blue Film With Requirements
Listed on Performance Specification MIL-PRF-22019D
Background: Cortec Corporation is
seeking to have Cortec VpCI-126 listed on qualified product
list MIL-PRF-22019D. The
process of getting listed, involves Cortec Corporation performing
the requirement tests as listed in performance specification
MIL-PRF-22019D. Upon attaining results in compliance with what is listed in
performance specification MIL-PRF-22019D, Cortec Corporation
will submit product to Naval Air Systems Command. Naval Air
Systems Command will then repeat testing to confirm results
attained by Cortec Corporation.

4.6.7 Storage Stability
Cortec VpCI-126 Blue film was wrapped
in one layer of MIL-PRF-131 class 1 barrier material and stored
for exactly one year. Upon removal, the following tests were
conducted using the Cortec VpCI-126 Blue film. Seam Strength Test (as received); Seam Strength (sealed after
aging at 160 deg F for 12 days and tested at room temperature);
Vapor Inhibitor Ability Test; Transparency Test (as received);
Transparency Test (after aging at 150 deg F for 12 days and
tested at room temperature).
