Abstract

Zur Herstellung von formaldehydarmen tanningebundenen Holzspan- und Faserplatten mit auf ein Minimum reduzierter Formaldehydabgabe wird das Tannin teilweise in pulveriger Form und teilweise in flüssiger Form auf die Späne bzw. Fasern aufgebracht, anschließend werden die so hergestellten Platten dann mit formaldehydaktiven Stoffen behandelt bzw. besprüht und ggf. gestapelt.
