Introduction
Metalizing is the premier, low life-cycle-cost (LCC) protective coating for steel structures. It is a more effective means of protecting steel than painting and re-painting and is certain to reduce bridge maintenance expense over the long-term. more...
Paint's Perpetual Problems
In this section we will periodically post news from the world of paint! We hope to interject a little humor as well ... at the expense of paint, of course. more...

Achieving Long Term Coating Performance
- Recently, an article, Achieving Long Term Coating Performance, appeared in the September 2000 issue of the newsletter Metalizing for Corrosion Control. In their article Bob Kogler and Carl Highsmith describe a twenty-year evolution of a life-cycle-cost (LCC) philosophy for bridge coating materials and processes. Government regulation and industry and technical factors converged during this period to bring metalizing out of obscurity. more...

- Ohio Was One of the First - Recent photos indicate that the coatings are in excellent condition. more...
- Definition of Metalizing Sealer - Metalized aluminum and zinc coatings corrode naturally. The corrosion products that form seal any porosity in the sprayed-metal coating. This natural sealing, by the formation of the corrosion products, consumes the metal coating. A paint sealer may be used to artificially seal the pores in the metal coating. more...

Three authors reply to the question: How do you measure the DFT or WFT of a film-forming sealer applied to a metallised coating (e.g., flame-sprayed zinc)?" This MUST be read by everyone in the metalizing business! more...
