Preparatory actions

What is it for?

The preliminary phase involved the scale-up optimization of the formulations for the final application on small and medium-sized ship hulls.

Action A1

The action was completed by the Coordinating Partner UNITOR, University of Rome Tor Vergata, by following the steps:

  • Fine tuning of the amphiphilic character and the surface micro-structure, thickness and roughness of the coating
  • Characterization on a laboratory scale of the anti-fouling capacity
  • Mechanical evaluation as well as adhesion to different substrates such as fiberglass and steel
  • The control of the rheological properties and aesthetic finishing mainly for spray/airless application technologies

The lab-scale results obtained on the applied formulations drive towards a wide range of customizable solutions, showing a high replication potential.


The action was completed by the partner, University of Rome Niccolò Cusano, with the realization of:

  • A preliminary evaluation of the ecotoxicity of the paints on the optimized formulations by using chlamydomonas reinhardtii wild alga.

The ecotoxicity tests indicated that the cells visibly died in the case of a biocide paint coated support, as visible from the change of the algal solution. The absence of toxic activity towards algae and micro-organisms of biological reference was confirmed.
