The company offers a wide range of solutions, from high grade tin-free self-polishing antifouling Sigmaplane Ecol, to solvent free tankcoating systems, such as the combined spray and fill solvent free epoxy Sigmaguard CSF and Sigmaguard BT for ballast tanks. An interesting example of successful treatment was on the 136,000-dwt ore carrier Daghild. When owner John P. Pedersen took over this 17-year-old ship, the condition of the main weather decks and hatch tops was report- edly poor. Not much of the previous coating sys- tem remained, and extensive pitting had occurred. The owner realized the situation had to be addressed quickly, and wanted to carry out the upgrade work at sea using the ship's crew and its own equipment. The process adopted was to extensively machine descale the total area, followed up by progressive grit blasting. Sigma Multimastic — a self-priming surface tol- erant epoxy coating — was then directly spray- applied in two coats, finishing with a standard red-brown shade.

The new GelTek molded boot reportedly prevents corro- sion-causing electrolytes, such as salt water and spray, water vapor or exhaust gases from coming into contact with metal joints on industrial equipment. GelTek was tested by the Naval Surface Warfare Center (Port Hueneme Division) on waveguide flanges aboard ships.

From past experience, California Marine Diesel was naturally skeptical that a cleaning agent would be able to restore the air cooler to opti- mum performance, given the difficulty of clean- ing the air side of such large coolers. As the com- pany noted, it is usual to replace it with a new one. In this case, upon visual inspection, it was not possible to see daylight through any part of the air side. The air cooler was sent to the Rusteco Service Center for cleaning, and upon its return and reinstallation, it was found that the cleaned unit performed as well as a new unit.
