Wetting Property and Resistance to Chloride Ion Permeability of Paint Films in Engineering Structure Protective Coating Systems under Marine Climate Condition

The paint was selected from in the typical protective coating system. Wettability and resistance to chloride ion penetration of the film were tested. The results showed that the amount of chloride ion penetration is related to the thickness of coating. Further experiments and discussion are needed to study on the coating film-forming material and coating pigments, filler shape affecting on the penetration of chloride ion.
