Hubble Bubble Rising

by Carl Reed, Greenman-Pedersen, Inc. (GPI), and Dr. Mike O’Donoghue and Vijay Datta, MS, International Paint LLC

This article examines the flaws of the current system of establishing and using specifications and testing. Because these flaws are so odious, a “better way” will be proposed in order to provide the end user real value in the use of protective coatings. Three tests will be discussed as illustrative examples of the flaws in the current system of using specifications and testing. These three tests are accelerated corrosion testing, pull-off adhesion testing, and constant stress, chemical immersion testing. Notwithstanding, this monograph will show how these tests, as examples of testing in general, can be used in a manner that provides the end user real value.


Inhalation Hazards Associated with Abrasive Blasting

by Thomas E. Enger, MS, CSP, CHMM, Clemco Industries Corp.

This article explores the inhalation hazards associated with the blast media, substrate, and coating used and treated in abrasive blasting from multiple aspects including inhalation hazards from the treated surface (paint, epoxy, heavy metals), hazards from abrasives (sand, coal slag, steel grit, garnet, crushed glass, organics and polymers) and hazards from breathing air (carbon monoxide, oil, odors and mist).


Moving Beyond the 25-Year Coating

by Todd Williams and Ahren Olson, Covestro LLC, and Paul Vinik, Florida Department of Transportation

Zinc-rich primers have been well studied, yet specifying inorganic (IOZ) or organic zinc (OZ) for three-coat systems remains a highly debated topic. During the 1960s and 1970s inorganic zincs became the dominant primer in North America and published literature shows IOZ outperforming OZ in three-coat systems. The study presented in this article focuses on evaluating two variables within the traditional ZEU system that could impact performance — zinc-rich primer type (i.e., inorganic or organic) and topcoat chemistry.
