Abstract
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.
