Powder Coating Preparation Control of Surface Defects for FEVE Resin Systems

Paint formulators can spend an immense amount of time and resources screening various additives to remedy defects on cured surface coatings. However, in some cases, the preparation methods prior to application may be the cause of significant surface defects for powder coating systems. We compared various preparation methods to changes in surface appearance and physical performance for FEVE resin-based powder systems over metallic substrates. This study will utilize accelerated corrosion testing that includes ASTM G85 prohesion and electrochemical impedance spectroscopy (EIS) to evaluate how a powder system’s preparation can affect the topcoat’s overall performance.
