2.2.1 It is suggested that hot dip galvanizing
should be employed as the primary means for corrosion protection for
these PMAs. The galvanized items should be subsequently coated according
to the coating manufacturer’s recommendation.
2.2.2 Where protective coating is applied as the
sole means of corrosion protection for these items, the Performance
standard for protective coatings for void spaces (resolution MSC.244(83)), should be applied
to the extent possible. In such case, the protective coating should
at least comply with the requirements for the coating system (epoxy-based
system) and total NDFT (200 μm) of that standard.
