Cold Application of EcoAir® VpCI™-337
Background: TNT currently packages automobile parts in Italy and ships the parts to South America for assembly. During the winter season in Italy, the parts are cold, 0° to -10° C and with high levels of humidity. They would like to find water based rust preventative to apply to cold metal that gives corrosion protection.
Purpose: Determine if EcoAir® VpCI™-337 can be applied to cold steel parts and prevent corrosion during shipping.
Materials: Carbon Steel Plates
EcoAir® VpCI™-337
5-gallon bucket
Method: Environmental Chamber, (105° F, 95-100% Relative Humidity)
Procedure: The testing was designed to simulate the environment experienced during shipment from Italy to South America for the parts from TNT.
- Two carbon steel panels were cleaned and packaged in 5-gallon buckets.
- The buckets were placed out of doors for 48 hours in temperatures ranging from -5° C to -12° C. One sample was left with no VpCI protection, the control, and the other bucket was fogged with EcoAir® VpCI™-337.
-
After 4 hours out of doors, the samples were placed in the environmental chamber, 105° F, 95-100% Relative Humidity. Periodically the samples were inspected, and after 12 days, the samples were removed from the environmental chamber. The samples were inspected, pictures were taken and a report was written.
Results: The following results were found:

Conclusion: EcoAir® VpCI™-337 protected the cold steel parts quite well. This testing suggests that EcoAir® VpCI™-337 applied to TNT’s parts cold should provide protection for shipments to South America.
