Selektope is a substance developed to avoid fouling of barnacles and other shell forming animals on boats and ships, a so called antifouling substance. It has proven effectiveness in concentrations of about 0.1 % w/w.
How does it work?
The antifouling effect is exerted through stimulation of the barnacle larvae’s swimming behaviour. It thereby makes the larvae unable to attach to a surface painted with Selektope.
As soon as the barnacle leaves the surface the effect disappears, i .e. it is a reversible effect.
Low concentration= high effect
Due to the low concentration needed, Selektope does not compromise the paints chemical structure, colour or other cooperative biocides involved.
Selektope is under evaluation according to the Biocidal Products Directive for approval as an antifouling biocide within EU. Aprovals in Japan and Korea were granted in 2011. Notification in China is ongoing.
