Tests at the Oosterschelde since 2006 and still free of fouling. The blue panel is a Thorn-D® foil. It is clearly visible that the untreated panel is covered by barnacles. |
Thorn-D® is a patented non-toxic antifouling technology that provides a physical barrier for biofouling. By applying very specific short fibres (‘thorns”) on a surface, the surface becomes prickly and unattractive for fouling organisms to settle.
Thorn-D® has proven to be effective by testing at different locations of the world.
Instead of killing fouling organisms, Dr. Breur came up with the idea of preventing the organisms to settle.
The basic thought behind Thorn-D® is that a combination of prickliness and swaying of Thorn-D® fibers makes the surface unattractive for organisms to settle. To fully understand the mechanism, one has to discern the three different categories of settlement:
