This page contains some useful technical information regarding the processes and chemicals we currently use in Zinc Plating.
The data below relates to corrosion testing in accordance with ASTM B117 procedures, 5% neutral salt spray, and deposit thickness 8µm.
Silicate post dips and lacquers can add 100-250h to the above values. Protection of steel substrates (red rust corrosion) is proportional to the deposit thickness.
|White (hours)||6 – 24||72 – 96||96||96|
|Red (hours)||24 – 48||300||350||504|
