What results have been obtained with Plascoat PPA 571 in salt spray tests?
The salt spray test to ISO-7253/ASTM B117 (5% sodium chloride solution at 35C) was carried out both on pre-treated Plascoat PPA 571-coated steel panels with a cross-cut and on PPA 571 coated aluminium panels. The subsurface corrosion at the cross-cut after 1,000 hours was 0 mm with the aluminium panels nad <1mm with the steel panels.
