A process to form a multilayer article comprising pressing a stack comprising two or more panels, wherein each panel comprises a surface layer and a substrate layer, wherein a side of the surface layer is contacted to a side of the substrate layer, and wherein the contacting sides of the surface layer and substrate layer have a fast setting adhesive disposed there between; and wherein pressing comprises applying uniform pressure to the stack orthogonal to the plane of the panels, at ambient temperature and for a time of 0.1 to 20 minutes, and with no subsequent hot pressing. Articles prepared using the method are also disclosed.
La présente invention concerne un procédé, permettant de former un article multicouche, qui consiste à comprimer une pile comprenant deux panneaux ou plus. Selon le procédé, chaque panneau possède une couche de surface et une couche de substrat, une face de la couche de surface vient au contact d~une face de la couche de substrat et les faces de contact de la couche de surface et de la couche de substrat ont des adhésifs à prise rapide disposés entre elles. Selon ledit procédé, la compression consiste à appliquer sur la pile une pression uniforme orthogonale au plan des panneaux, à une température ambiante et pendant un laps de temps compris entre 0,1 et 20 minutes, sans être suivie d~un pressage à chaud. L~invention se rapporte également aux articles obtenus à l~aide de ce procédé.
