RECC System Benefits

13. Benefits of Rare Earth Non-Cr System
RECC deposits darker in areas of unpassivated / exposed metal
(Areas of weakened passivation, rivets, abrasion, etc are conversion coated)
(Areas of previous passivation are reinforced for adhesion/max corrosion protection)

14. Benefits of Rare Earth NON-CR System
- Water-Break Free Surface
Surface Remains Wet
> 15 Minutes
- Well Cleaned/Pretreated Surface
F-16 Application – Hill AFB
C-130 Application – Hill AFB
