  • Method of sealing surfaces
    Patent number: 10087342
    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.

  • Surface covering which is hardened in several stages
    Patent number: 8153264
    Abstract: The invention relates to a method of sealing at least part of the surface of an article, comprising the steps of (a) applying a layer of a radiation-curable melt based on a moisture-crosslinking polyurethane to at least part of the surface of the article, and (b) irradiating the melt layer. The invention further relates to article surfaces sealed in this way, and also to the use of the abovementioned melt for surface sealing.
