“Laboratory Testing of Candidate Coating Systems for Protecting A 490 Bolts in One World Trade Center Construction” (PDF 178Kb) The construction of the new One World Trade Center (WTC) in New York includes exposed steel members and bolted splice plates. Accordingly, surface preparation and coating system selection for the bolt/washer/nut assemblies for the bolted connections was critical, since the splice plates would be visible. There was little published information on surface preparation and coating requirements for ASTM A 490 black bolts. Further, since on site surface preparation of bolted connections would be costly and labor intensive, the Port Authority of New York & New Jersey (Port Authority) investigated the viability of using a proprietary pretreatment process on the bolts prior to installation and coating application, in order to minimize on‐site surface preparation without adversely affecting coating system adhesion or performance.

“Fourier Transform Infrared Spectroscopy To Verify Chemical Consistency Of Industrial Coatings The Application Of Instrumental Comparative Methods” (PDF 230Kb) The use of Fourier transform infrared spectroscopy combined with knowledge of coating chemistry is key for assessing chemical consistency of industrial coatings. Incomplete knowledge of coating chemistry, improper sample preparation techniques and/or instrument use, as well as improper interpretation of infrared spectra can result in inconsistent chemical comparisons of batches used for initial qualification to field batches.

“Regulatory Update: Current And Emerging Trends In Occupational And Environmental Health” (PDF 301Kb) This paper takes a look at emerging environmental, health and safety issues that may impact painting contractors and facility owners. Specific topics include OSHA’s proposed revisions to the Hazard Communications standard, updated information on silica and hexavalent chromium, and expected rule making in 2010. Additionally, information will be provided on EPA regulatory actions related to NAAQS Lead and PM2.5 and other EPA regulations. Much of the information is taken directly from the respective agency’s published regulatory agenda, supplemented by anecdotal information gathered from various professional journals, seminars and conferences.
