Abstract (en)
[origin: DE19601401C1] A process for the continuous production of chipboard or fibreboard (I) from lignocellulose-containing materials (II) is claimed. (II) is in the form of chips or fibres and is impregnated with a NCO group-containing binder, formed into a mat and press-moulded in a heated press after precoating the press surfaces etc. with an external release agent (III). (III) consists of an aqueous suspension containing 5-40 wt.% talcum as the sole active release agent, with no surface-active substances.
