An external release agent for lignocellulosic composite panels or wood panels comprising a suspension of one or more synthetic or natural clays wherein the suspension medium can be either aqueous or nonaqueous and wherein wood strands, wood chips, wood fibers, or wood powder or their mixtures are utilized as raw materials for panel production.

Methods and systems for forming a thin-layer moisture-resistant fiber composite material involve pressing a mixture of fibers and resin between a pair of heated dies at least one of which includes a working surface coated with a hard ormosil coating including a cross-linked organically-modified silica network. The use of such coatings may yield composite sheet materials having improved surface quality, sharper edges, and greater draw angles than previously possible. Some systems for making thin-layer fiber composite materials may utilize ormosil coatings on various working surfaces of equipment coming into contact with the fiber and resin mixture, such as surfaces of machinery for mixing or conveying the mixture to the dies.

The present invention relates to a process for the production of lignocellulose materials via mixing A) of lignocellulose-containing particles or fibers, B) with organic isocyanate having at least two isocyanate groups or a mixture of these, and optionally with C) binders selected from the group of the phenol-formaldehyde resins, the aminoplastic resins, the protein-based binders, and other polymer-based binders, and mixtures of these, D) additives or a mixture of these, and E) plastics particles or a mixture of these, with the steps of: i.) scattering of the resultant mixture to give a mat, ii.) precompaction and heating of the mat during or after the precompaction process, and iii.) then hot pressing,
