Protección antiincrustante de estructuras sumergidas mediante recubrimientos formulados con 7-hidroxi-4-metilcumarina

Environmental regulations focus on the use of environmental friendly products to replace metallic biocides included in antifouling paints which are highly pollutant. A growing interest for searching and identifying efficient and benign antifoulants has being carried out.

For this reason, the compound 7-hydroxy-4-methylcoumarin was synthesized following Green Chemistry procedures and then, characterized by current organic analysis. In the laboratory, antifouling activity of this coumarin was estimated by settlement test, i.e., batches of mussels (Mytilus edulis platensis) were exposed to different concentrations of the compound. Results indicated that coumarin was effective on both, settlement inhibition and byssal thread.
