Hempel's product, known as Hydron Dynamic 0500, bases its advantages on Hydron's remarkable water-attracting (hydrophilic) property, which means that the coating can absorb up to 80 percent of its own weight in water when in contact with it. The new coating's aim is to alleviate the micro-roughness of a ship's hull. Hydron Dynamic is a clear coating and is initially intended for selected classes of vessels such as mammoth tankers and bulk carriers and for high-speed ships such as container carriers, LNG tankers, and passenger liners. It is expected that a mammoth tanker could pay off the cost of a Hydron Dynamic application in one month; a 15-knot tanker sailing between the Persian Gulf and Europe could save $15,000 on fuel by improved performance. A hydron coating, costing an estimated 36 p/sq yd, can be applied by a conventional airless spray in up to 100-micron thicknesses, cures in 0.5 h to 0.75 h, and has been applied in temperatures down to 3 deg C. An application of the new Hampel one-coat anti-fouling paint underneath is estimated at 84 p/sq yd.
