Abstract : The report supplements NCEL Technical Report TR-490 (AD-802 877), presenting additional results of the investigation of protective coating systems of various generic types that were applied to 10-foot steel panels. These simulated steel pilings were suspended from a corrosion dock in the mouth of Port Hueneme Harbor so that the bottom portion was in continuous immersion, the middle portion in the tidal zone, and the top portion in the atmosphere. Many of these same protective coating systems were also exposed on 10-foot angle iron panels driven in the surf of the outer harbor at Port Hueneme so that the top half of the panel was exposed to the abrasive action of the surf. Results are given for coating systems that were performing satisfactorily at the time TR-490 was issued as well as a number of additional coatings that have been exposed since then. Exposure times for the 87 coating systems exposed on the corrosion dock and the 65 coating systems exposed on angle iron panels in the surf ranged from 2 to 15-1/2 years. (Author)
