Abstract

Die Erfindung betrifft eine Imprägnierungslösung für Naturhölzer bzw. Holz- sowie Zellstoffprodukte, die die im Holz vorhandenen Säuren abbindet und neutralisiert, das Formaldehyd und andere Aldehyde im Holz sicher bindet und durch einen Zusatzstoff die Hydrophobierung des Holzes vornimmt. The invention relates to an impregnation solution for natural woods or wood and pulp products that the existing in the wood Acids binds and neutralizes the formaldehyde and others Aldehydes binds safely in the wood and through an additive Hydrophobization of the wood.
