Abstract: The present invention relates to a process for the preparation of a panel comprising ligno-cellulose particles such as a strand-like particles, comprising the steps of treating ligno-cellulose particles at least partially covered with epicuticular wax (2) with ozone (7) at a temperature of at least 30 degrees Celsius, mixing the resulting product with an water-based adhesive resin composition to obtain a resinated particle composition, and pressing and at least partially curing the resinated particle composition to obtain a panel.

Abstract: The invention relate to a process for forming a cured, partially cured or uncured thermosetting material, comprising: an irradiation step wherein the thermosetting material is exposed to electromagnetic radiation which to a significant extent is within the neat-infrared range in such a way that the temperature of the irradiated thermosetting material is brought to between 40° C. and 400° C., and a forming step wherein the irradiated thermosetting material is brought into a desired shape, whereby the forming step is executed during and/or subsequent to the irradiation step. The invention also relates to an apparatus for carrying out the said process and to a thermosetting material.

Abstract: The present invention relates to a process for the preparation of a panel comprising a ligno-cellulose containing strand-like material, comprising the steps of treating the ligno-cellulose containing strand-like material with a combination of UV-radiation and ozone, either in-situ or ex-situ, mixing the resulting product with an adhesive composition, applying the resulting mix onto a press-bottom, and pressing and at least partially curing the composition to obtain a panel.

Abstract: The invention relates to a resin impregnated paper substrate with crystalline triazine, preferable vapor deposited triazine. The crystalline triazine preferably is present in an amount of about 5 g/m2 or higher and about 100 g/m2 or lower. The invention further relates to a process for making a laminate comprising at least one cured layer of amine-formaldehyde resin and a paper, wherein a resin impregnated paper with vapor deposited triazine is submitted with one or more other layers to pressure and/or sufficient temperature to cure the resin and at least part of the triazine.

Abstract: The invention relates to an Oriented Strand Board (OSB), comprising a core layer and two face layers, whereby at least one layer comprises an adhesive composition, characterised in that the adhesive composition comprises a resin composition comprising urea and formaldehyde, whereby the resin composition further comprises melamine and/or an aromatic hydroxyl compound, wherein: the molar ratio of formaldehyde to the sum of melamine and the aromatic hydroxyl compound lies between 8:1 and 100:1; the molar ratio of formaldehyde to the sum of (NH2)2 and the aromatic hydroxyl compound lies between 1:0.2 and 1:2. The invention further relates to a process for preparing the OSB according to the invention.
