PPG Direct-to-Metal Coating

PPG (Pittsburgh) has introduced SPECTRACRON® SPM Series DTM (direct-to-metal) monocoat, a one-component coating that helps prevent corrosion to metal surfaces. Spectracron SPM is engineered for direct application to pretreated metal substrates while providing corrosion resistance that, the company reports, is comparable to traditional two-component primer-topcoat systems. The proprietary high-solids, high-gloss formulation also enables Spectracron SPM coating to be applied over pretreatment chemistries such as iron-phosphate, zinc-phosphate and zirconium at supplier-recommended weights. Flash times and cure temperatures for the coating are similar to those of current urethane topcoats, eliminating concerns about fast wet-on-wet application times and enabling the coating to work without constraints on existing paint lines.
