摘要:
The invention relates to a method and a device for producing parts (1) having a sealing layer (2) on the surface, and corresponding parts. Said method and device are improved in that the sealing layer (2) is applied to the surface in the form of a water-free and solvent-free reactive hot melt layer based on polyurethane and hardened by atmospheric humidity, and the inventive device comprises an application station (6), a transport device (5) and a smoothing station (8).

The invention aims at improving a method and a device (17) for the production of veneers (1) and veneered parts (13) and to veneers (1) and veneered parts (13). To this end, a sealing layer (2) is applied on the surface of the veneer (1) before further processing. The device (17) includes a veneer producing device known per se, a finishing station (6), a transporting device (5) and a polishing station (8).

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.

Proposed is a process for preparing a reactive polyurethane composition that is characterized in that in a first process stage, from an isocyanate-reactive polymer or mixture of isocyanate-reactive polymers with a fraction of at least 90%, preferably at least 95%, more preferably at least 99% by weight of linear molecules, by reaction with a polyisocyanate having a molecular weight
摘要:
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.
