On the Topographical and Performance Effects of Underblasted and Reblasted Carbon Steel Substrate

On the Topographical and Performance Effects of Underblasted and Reblasted Carbon Steel Substrate
Available for download

In this study, the effect on coating corrosion resistance after remediating an under-blasted then remediated to standard preparation is undertaken. In this work, it is proposed to under-blast one set of panels (~1 mil profile), blast to standard one set of panels (~3 mil profile) and remediate to standard a set of under-blasted panels (from ~1 mil profile to ~ 3 mil profile).

Past work by the authors studied the effects of remediating over-blasted substrates by reblasting with smaller abrasive perpendicular to the substrate and at acute angles followed by coating the substrate, exposing the coated panels to B117 Salt Fog Testing and evaluating the coating performance, topography of the blast profile, scribe creep corrosion and cathodic delamination. In this study, the effect on coating corrosion resistance after remediating an under-blasted then remediated to standard preparation is undertaken. In this work, it is proposed to under-blast one set of panels (~1 mil profile), blast to standard one set of panels (~3 mil profile) and remediate to standard a set of under-blasted panels (from ~1 mil profile to ~ 3 mil profile). Two different blast media, steel grit and coal slag, are used to prepare the test panels. Uncoated panels are evaluated for differences in topography and embedment of blast media using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and stylus profilometry. Panels are coated with a commercial two package epoxy and exposed to ASTM B117, Salt Spray Testing for 1000 hours. After exposure, the panels are evaluated for scribe creep corrosion and cathodic delamination.

The tank painting process for the interior of a petroleum and/or water storage tank requires proper coating selection, product application and inspection in order to achieve long-term service life. The primary cause of early coating failures in a painting project is often related to an application issue. The use of coating systems and linings formulated with Optically Active Pigments (OAP) can help to ensure correct application and inspection of the tank linings.

New Developments in Surface Profile Measurement for Blast Cleaned Surfaces

When protective coatings are to be applied to structures, it is important that the surface is clean and dry if premature failure of the coating is to be prevented and the full coating service life achieved. In many situations for both new build and repair of structures, blast cleaning of the surface is required to remove contamination and to create an anchor pattern to enhance the adhesion of the coating system to the substrate.

It was requested that exposure testing be completed on various high durability coatings products to evaluate gloss retention and color changes. Various systems were chosen to test, some with clear coats and some without. They were placed in cyclic UV/condensation testing, concentrated natural sunlight testing in Arizona, and outdoor exposure testing in South Florida.
