... that 3LPE coatings generally retained good adhesion to steel pipelines without being put into service, but complete disbondment of FBE primer to steel substrate have been observed, with some of them noted even after 2-3 years in service. A review of related literatures and broadly used 3LPE standards...

... ABSTRACT Zinc rich primer coatings (ZRP) have become widely used since the 1980’s for corrosion mitigation. The effectiveness of the ZRP coating strongly depends on the pigment volume concentration and bonding to the steel substrate. Beneficial cathodic polarization occurs when the dispersed...
