Abstract: The invention relates to a method for producing a composite film with a polyurethane-based reactive hot-melt layer using a coating facility, having the steps of a) optionally applying a primer onto a support material; b) applying the polyurethane-based reactive hot-melt layer onto the primer or directly onto the support material; c) applying a lacquer layer onto the polyurethane-based reactive hot-melt layer in order to produce the composite film on the support material; d) optionally embossing the composite film on the support material; and e) separating the composite film from the support material. The invention additionally relates to a composite film which can be obtained by such a method and to the use thereof.

Abstract: The invention relates to a device (1) for melting a hot-melt adhesive (3), comprising a heating plate (5), a plunger (7), the plunger (7) comprising a plunger end face (9), and a mounting (11), wherein the mounting (11) is suitable for receiving a storage container (13), which has a rigid lateral wall (15) and two opposite side faces (17, 19) and contains the hot-melt adhesive (3), in such a manner that the hot-melt adhesive (3) is arranged between the plunger (7) and the to heating plate (5), and the plunger end face (9) and the heating plate (5) are arranged opposite one another, wherein the heating plate (5), the plunger (7) and the mounting (11) are so dimensioned that the storage container (13) having an inner volume (21) of more than 50 L can be received. The invention relates further to a method for melting a hot-melt adhesive.

Abstract: The present invention relates to a process for the production of structured surfaces via application of a layer made of reactive hotmelt and then embossing of the surface, and also to an article thus produced.

Abstract: The present invention relates to an article whose surface has been at least partly sealed and to methods of its sealing, the sealing layer comprising a reactive melt layer and a coating layer. The invention provides a method of sealing at least part of the surface of an article, comprising the steps of: (a) applying a reactive melt layer based on polyurethane to at least one part of the surface of the article; (b) smoothing the reactive melt layer; and (c) applying a coating material to form a coating layer on the reactive melt layer, the coating layer being applied before the full curing of the reactive melt layer.

Abstract: The present invention relates to a process for producing high-gloss surfaces on at least one portion of a substrate area, where the steps comprise (a) applying a layer made of a melt to at least one portion of the substrate area; (b) polishing of the applied layer of melt; (c) applying at least one lacquer layer to the polished layer of melt by means of a curtain-coating process; and (d) hardening the layer structure applied. The invention further relates to articles obtainable by this type of process.
