European patent office has granted the inovative solution for wood preservation. The object of this patent is fact that addition of hydrophobic agents (carboxylic acid) to the preservative solution can significantly improve fixation of wood preservatives. On the basis of this patent, company Silvaprodukt has launched new commercial preservative solution Silvanolin. In jear 2008, 300.000 L of this preservative was produced.

This paper was presented on the annual meeting of International Research Group for Wood Protection (IRG WP). Boron compounds are one of the key ingredients in commercial wood preservatives. However, they leach from wood, therefore their fixation needs to be improved with addition of hydrophobic ingredients. In this part of research, boron compounds were combined with Polyvinyl acetate emulsion. This emulsion reduce boron leaching and performance against wood decay fungi but not that effective as montan wax.
