Abstract
A method for coating a surface comprises applying a layer of coating composition onto the surface, mechanically forming parallel ribs on the layer, and simultaneously polymerizing the layer with ultraviolet radiations. The coating composition comprises a mass percentage of urethan-acrylate oligomer, with an average molar mass in number between 1000 and 5000 g·mol−1, between 35% and 75%. The coating composition further comprises a mass percentage of a diluting agent, copolymerizable with urethan-acrylate oligomers, between 15% and 60%, and a mass percentage of pyrogenic silica between 0.5% and 5%.
