    摘要: The present invention relates to novel formulations for adhesive compositions and to adhesive compositions, especially for a hybrid adhesive comprising at least one mixture of an amino resin and at least one polyether, and to the combination of this mixture with isocyanate and to the use of polyethers in adhesives based on amino resins. These adhesive compositions are especially suitable for use as adhesives for woodbase materials, especially OSB sheets, fiberboard or particleboard. In a further aspect, the present invention relates to processes for producing such woodbase materials from lignocellulose-containing comminution products, especially to processes for producing OSB sheets, wood fiberboard or particleboard, wherein the lignocelluloses-containing comminuation products are contacted with the inventive adhesive composition and then the woodbase materials are obtained by pressing with heat treatment. Finally, the present invention is directed to correspondingly obtainable woodbase materials.
