21/2with minimum surface profile of 50µm.
• Apply Corroglass 600 Series to a min.dft of 1.5mm.
• Thickness check and spark test to 19Kv Hv-AC.
During the service life, which comprised external exposure to seawater (immersed, splash zone and atmospheric), and internally, seawater with a low hydrochlorite dosing (4%), the coating has not shown any tendency to undercut, and only minor mechanical damage was needed to be repaired.
The sustained performance of Polyglass Standard under adverse operating conditions demonstrates the products’ suitability for use in diverse applications throughout industry.
