This study assessed the influence of graphene oxide on the adhesion performance of an epoxy primer applied to metallic structures. A robust experimental methodology was developed, incorporating critical variables such as abrasive type, surface profile, and dry film thickness, adhering to international standards ASTM and SSPC. ASTM A36 steel panels were prepared using sandblasting and grit blasting techniques. Surface roughness was measured with Testex tape, and dry film thickness was controlled with a UNI-T 343D gauge, maintaining a tolerance of ±20% around the nominal target of 10 mils. Adhesion tests performed under ASTM D4541 standards revealed a superior performance of the epoxy primer with graphene oxide. Panels coated with this primer achieved average pull-off strengths of 933 PSI on sandblasted surfaces and 1200 PSI on grit-blasted surfaces, surpassing the 740 PSI and 750 PSI results recorded for the Jet 62ZP primer. The enhanced adhesion observed was attributed to the higher surface roughness generated by grit blasting (2.90-3.70 mils), which improved mechanical interlocking, and the cohesive properties of graphene oxide, which strengthened the primer's internal structure and resistance to delamination. In conclusion, incorporating graphene oxide significantly improved the adhesion properties of the epoxy primer, demonstrating its potential as an innovative additive for advanced anticorrosive systems in demanding applications.
