ni? cant cost ef? ciencies for spot repair work. Engineered to provide ease of use and economical application char-acteristics, the new product possesses a practical overcoating window and, with its ability to be applied at temperatures down to 5°C (41°F), offers year round application potential. Sijmen Visser told MarineNews , SIGMACOVER 580 provides an outstanding spot-re- pair solution for the dry dock market, due to its unique functionality. It is an epoxy coating for underwater hulls that functions both as an anticorrosive and also 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 dur-ing routine maintenance and repair dry dockings. Ultimately, this provides signi? cant budget savings for the ship- owner 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 per- formance, and an outstanding return on investment.? With shipowners under increasing ? nancial pressure, one source of expen- diture for any shipowner after delivery of a vessel is the cost of dry dockings. While paint costs are relatively minor, the total of surface pre-treatment, ap- plication costs, time in the dry dock and being off-hire adds up signi? -cantly. Visser adds, SIGMA 580 is 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, SIG- MACOVER 580 can be applied to pre- blasted areas for spot repair in a single coat at a dry-? lm 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 speci? cation and eliminating the need for a second an-ticorrosive or tiecoat layer, application time is reduced and productivity is in- MN 89www.marinelink.com MN Sept2013 Layout 82-95.indd 898/29/2013 4:27:43 PM
