摘要:
Disclosed is the production of isocyanate-based or silane-functional adhesive and/or coating materials in the form of reactive single-component granulates and the use thereof. In particular, the reactive one-component coating-material and/or adhesive granules of the include at least one isocyanate-reactive starting polymer and at least one diisocyanate and/or polyisocyanate. Optionally, the granules of the invention may further include at least one catalyst and/or at least one wax and/or at least one resin and/or at least one preferably non-isocyanate-reactive polymer. The granules of the invention may contain an excess of diisocyanate and/or polyisocyanate which amounts to 0.5% to 30 w %, and is preferably generated by free terminal isocyanate groups.

摘要:
The invention relates to a method for permanently joining an essentially flat support material to a substrate, in particular for laminating a plastic film to a metal substrate, wherein the at least essentially flat support material and/or the substrate is/are initially impinged upon by a connecting agent, preferably, an adhesive and subsequently the support material and the substrate are brought together in such a manner that the support material is permanently connected to the substrate, in particular, the plastic film is laminated on the metal substrate, and optionally, measuring and/or shaping of the thus formed composite material is carried out.
摘要:
The invention relates to an adhesive system which is based on a non-reactive thermoplastic adhesive melt. The adhesive melt (A) contains a mixture of at least two metallocene-catalytically produced copolymers which are different from each other, and which are based on at least two a-olefins, whereby the copolymers of the mixture, which are different from each other, have different melt indices (MFIs); (B) optionally, at least one additional polymer; and (C) optionally, at least one resin and/or at least one wax. The inventive adhesive system is particularly suitable for use in the wood and furniture industry, e.g. for covering profiles or for gluing edges, in particular, by comparing copolymer adhesives to EVA melt adhesives which are used in a traditional manner, and the system enables considerably lower application temperatures to be used, and at the same time exhibiting improved adhesion capacity.
