Improved Final Rinse for Zinc Phosphate Pretreatment Coatings
Abstract
In an effort to increase corrosion resistance of TT-C-490, Type 1, zinc phosphate pretreatments, a study was conducted on inhibitors added to the final rinse. Salt spray testing and tropical exposure studies indicated that a final rinse containing sodium chromate produced an increase in underfilm corrosion resistance with one coat paint systems.
