1517894 Coated marine surfaces O RASMUSSEN 24 Feb 1977 [26 Feb 1976] 07777/ 77 Heading B2E Ships and sub-aqueous surfaces are protected against corrosion by application of a coating wax which consists of several layers of wax applied in sequence, the layers differing in physical properties so that they can be removed successively after they have become subjected to growth formation. One or more of the wax layers may contain an anti-fouling composition and the wax may be applied as a melt or a dispersion by immersion or spraying. The layers may be removed by brushing, the pressure of brushing being regulated in accordance with the layer to be removed or by the application of water whose temperature is adjusted in accordance with the melting point of the layer to be removed. |
