Bio-Dur 561 Rises To The Challenge A large, oil-fueled power station located on the Gulf of Mexico in California receives fuel oil from tankers which unload at a deepwa- ter terminal. The discharge termi- nal is built at the end of a 1.2-km. long concrete pier built on 30 and 36-in. diameter steel pilings. The integrity of the pier is critical to the operation of the power sta- tion. In order to maintain the pro- tective coating system, it was nec- essary to apply a barrier type sys- tem under conditions of vigorous wave action or complete submer- sion. Because of the size of the project, old-fashioned "splash-zone" type putties were too difficult and slow to apply. Bio-Dur 561 is formulat- ed to be of a thick and pasty, but easily spreadable viscosity. Using putty knives, divers were able to obtain a consistent 30-50 mm. thickness under all conditions — even at the waterline when applying in wave action. Bio-Dur 561 was applied over the steel piling surface which had been freshly blasted using 4,000 psi water with entrained river sand abrasive. The surface obtained ENVJROJ/AC. sewage systems solve all your marine sanitation needs.

The divers and other workers employed in this project had little previous experience in this type of work, but were reportedly able to properly mix and apply the Bio- Dur 561 and obtain an excellent result. Under the conditions of application in approximately 65- 85 degree F water, the Bio-Dur 561 cured to a firm film after six to three hours, respectively, and was hard overnight. Wave action reportedly had no effect, even immediately after application, before any curing had taken place. The "wind and water" area of this structure is now protected with 30 -50 mm. of tough, impermeable and tenaciously attached epoxy coatings. According to reports, the work was performed with excellent productivity and without the need for complicated mixing or applica- tion equipment.

(APS), which the company claims will "re- volutionize the chemical and products carrier indus- try's think- ing." The tank coating, dub- bed Marine- Line, "elimi- nates the re- quirement for stainless steel tanks and the currently-used ranges of spe- cialty epoxy or inorganic zinc sili- cate coatings," said Don Keehan, technical director. The bottom line is potential cost savings and improved earnings. MarineLine is a high perfor- mance tank lining, formulated with the patented Siloxirane poly- mer resin technology. This cross- linked aerospace polymer struc- ture is engineered to provide improved protection against corro- sion and contamination by total prevention of cargo permeation. The coating can reportedly han- dle the marine environment and virtually all sea-approved bulk car- goes. The total range is available in the company's Marine Tank Lining Guide, which lists more than 4,000 chemicals and prod- ucts.
