Historically the focus has been on the adverse anions (chlorides, sulfates nitrates) with little attention
Aggregated FeS and ionically bonded FeCl2 is a pervasive, difficult, and high-liability issue for pipeline,
petrochemical, power, shipping, and other industries. Situational variations (meteorological, geographical,
seasonal, etc.) can confound conventionally specified surface preparation attempts to achieve perfect or
near-perfect metal cleanliness, thus reducing expected coating life by 30 to 75 percent. Because
conventional surface preparation processes have historically been unable to adequately relieve
microcontamination of metal surfaces, organizations have settled for an uneasy balance between economic
and physical feasibilities that exclude the possibility of achieving ideal surface preparation outcomes and
rely more heavily upon barrier coatings to supply needed corrosion control.
