Effects of Surface Preparation Methods on Adhesion of Organic Coatings to Steel Substrates

by A.W. Momber, S. Koller, and H.J. Dittmers

A number of parameters affect the adhesion of coatings to steel substrates. In this study, the authors explore surface preparation factors suitable for evaluating the quality of a steel substrate after dry abrasive blast (AB) waterjetting (UHP), and the combination of AB and UHP into a single process (UHPAB).

Case History: No Fuming When Concrete Is Etched at Operating Plant

by David A. Hunter and Doug Smestad

Coating concrete is critical at many industrial facilities. Coatings on concrete give facility managers greater ability to control cleanliness in the removal of oil and grease, disinfection for food product facilities, or radioactive decontamination of nuclear facilities. Concrete is also coated for safety concerns, such as the need to increase slip resistance of the concrete surface due to build-up of contamination from operations.

Editorial: Responsibility

by Bill Shoup

Just the other day, an employee came into my office and told me bluntly that he had made a mistake. Of course, my first reaction was “This is not good.” The employee then explained exactly what had happened, and while the mistake was cause for concern, it was not a really serious matter. I told him to call the affected owner, tell him exactly what happened, and then call the contractor to do the same.

Case History: Tape and Topping Get a Grip on Containment Problem

by Lori R. Huffman

A Niagara Falls, New Yo r k manufacturer of chlorine and caustic soda used a fluoropolymer tape system and novolac epoxy-vinyl ester topping to replace a rigid fiberglass system on a concrete loading pad (Figs. 1 and 2) subject to constant impact and wear. Olin’s Chlor-Alkali Products’ plant produces chlorine, caustic soda, hydrogen, sodium hypochlorite, hydrochloric acid, and spent sulfuric acid. After using traditional, rigid fiberglass-based systems on the concrete secondary containment area of the loading pad and not getting the service life desired, the company turned to a fluoropolymer tape and epoxy novolac-vinyl ester system that offered ease of installation and resistance to harsh chemicals.
