Surface treatment of wood was carried out using acryl-silicon type resin including didecyl dimethyl ammonium tetrafluoroborate (DBF), boron-containing quaternary ammonia compound. Surface-treated wood specimens were exposed laboratory decay resistance tests after completing a 10-cyle severe weathering process. In laboratory decay resistance tests, one brown-rot decay fungus, Fomitopsis palustris and one white-rot decay fungus, Trametes versicolor were used. The specimens were also subjected to laboratory termite resistance tests using subterranean termites, Coptotermes formosanus. Wood specimens treated with 2% DBF and resin containing preservative solution showed improved decay and termite resistance suggesting that the preservative solution at 2% DBF concentration provides lasting protection against wood degradation owing to the amount of DBF remaining in the wood after severe weathering process. However field tests are needed to determine the performance of surface-treated wood with DBF and the acryl-silicon type resin in more realistic conditions.

Oberflächenbehandlung durchgeführt mit Didecy – dimethyl – ammonium – tetrafluorborat (DBF) in Kombination mit Acryl - Silicon - Harz als Schutzmaßnahme gegen biologischen Abbau und Termitenbefall von Holz


Oberflächenbehandlung von Holz wurde mit einem Acryl-Silikon Harz einschließlich Didecyl – Dimethyl – Ammonium – Tetrafluorborat (DBF) vorgenommen, eine borhaltige quaternäre Ammonium - Komponente. Oberflächenbehandelte Holzproben wurden nach dem Durchlaufen 10 vollständiger strenger Witterungszyklen im Labor Fäulnisresistenztests unterzogen. Dabei wurden ein Braunfäulepilz Domitopsis palustris und ein Weißfäulepilz, Trametes versicolor benutzt. Mit denselben Proben wurden im Labor auch Termitenresistenzversuchen mit der unterirdischen Termitenart Coptotermes formosanus durchgeführt. Proben, die mit 2% DBF und einem konservierungsmittelhaltigem Harz behandelt waren, zeigten verbesserte Fäulnis- und Termitenresistenz, was nahe legte, dass die Konservierungslösung mit 2%iger DBF - Konzentration dauerhaften Schutz gegen Holzabbau liefert, auf Grund der Menge an DBF, die nach dem strengen Witterungsprozess im Holz verbleibt. Um die Dauerhaftigkeit der Resistenz von Holz, dessen Oberfläche mit DBF und Acryl-Silicon - Harz behandelt wurde, festzustellen, sind allerdings Freilandversuche unter wirklichkeitsnahen Bedingungen erforderlich.
