Abrasive Contaminants and Their Effect on Coating Performance

Abstract

Previous National Shipbuilding Painting Research demonstrated that substrate residues from salt contaminated slag abrasives cause rust-back and a possible reduction of coating life. This study characterizes eight (8) commercially available abrasive products for the water lechate conductivity chloride and sultate content and their effect on rust-back and coating performance in ambient and pressurized deionized water immersion. Four copper slag products were examined petrographically to identity the minerals in the slag particles and to determine it tree copper was present Scanning Electron Microscopy - Energy Dispersive X-Ray Elouresence (EDXRE) analysis was used to identity slag constituents.
