PPG Industries' protective and marine coatings business has announced the launch of SIGMACOVER™ 580 coating, an innovative epoxy anticorrosive/tiecoat that can deliver considerable savings and improved productivity at dry dockings.
SIGMACOVER 580 coating is engineered to provide ease of use and economical application. It offers a practical overcoating window and, with its ability to be applied at temperatures as low as 5 C (41 F), supports year 'round application.
The new coating "provides an outstanding spot-repair solution for the dry dock market due to its unique functionality," according to Sijmen Visser, PPG global marketing manager, marine. "It is an epoxy coating for underwater hulls that functions both as an anticorrosive and as an antifouling tiecoat. This dual-use formulation means that it can be overcoated directly with a range of antifoulings and is suitable for use during routine maintenance and repair dry dockings. Ultimately, this provides significant budget savings for the shipowner and can dramatically reduce time in dry dock. For areas that need spot blast of 40 percent or less, it gives customers excellent value, superb performance, and an outstanding return on investment.”
Visser added,“We know that shipowners are under pressure from a number of factors, and one source of expenditure for any shipowner after delivery of a vessel is the cost of dry dockings. Although the costs of paint are relatively minor, the total of surface pretreatment, application costs, time in the dry dock and being off-hire adds up significantly. Therefore, we have worked with our product specialists to come up with a product that can reduce dry dock time and ensure a fast turnaround in order to reduce some of the above factors.”
Once a vessel is in dry dock, SIGMACOVER 580 coating can be applied to pre-blasted areas for spot repair in a single coat at a dry-film thickness (DFT) of 250 microns (9.9 mils). Once this layer is dry, the antifouling paint can then be applied directly over it. By simplifying the underwater hull specification and eliminating the need for a second anticorrosive or tiecoat layer, application time is reduced and productivity is increased resulting in up to 50 percent cost savings, Visser said.
“During a standard dry docking, the use of SIGMACOVER 580 [coating] not only saves the application cost of a second anticorrosive coat, but also reduces dry dock costs and off-hire costs," Visser said. He added that additional savings are realized in paint consumption as there is less overlapping, less overspray and less waste. "Ultimately, the efficiency that the product provides enables the shipowner to put the vessel back into service quickly, thereby maximizing its revenue-earning capacity.”
