"Two coating materials, each with and without the addition of a vapor phase corrosion inhibitor (VCI), were tested by KTA. There was no decrease in tensile adhesion
strength properties for either coating material due to the addition of the VCI agent. Addition of the VCI agent to the MIL-DTL-24441 primer resulted in a measurable reduction in the degree of
coating failure observed at the “X” scribed areas on both the rusted and white metal substrates. The MIL-DTL-24441 primer with VCI agent provided better resistance to corrosion than
the
Sherwin-Williams zinc phosphate primer with respect to both rust creepage and overall degree of rusting. (Link)
