1. A method for mounting an edge band onto at least one narrow side of a workpiece in the form of a panel by means of adhesive bonding, wherein
(a) first, the edge band is provided, on its side to be joined to the workpiece with an adhesive layer which can be activated by means of laser radiation, wherein the laser-activatable adhesive layer is obtained starting from a dispersion or solution of at least one adhesive polymer to which at least one laser radiation-absorbing additive is added,
wherein the dispersion or solution of the adhesive polymer used in method step (a) for providing the edge band with a laser-activatable adhesive layer is formed on an aqueous basis or organic basis and comprises the adhesive polymer in an amount in the range from 5 to 90 wt. %, based on the dispersion or solution,wherein the adhesive polymer is selected from homopolymers and copolymers selected from the group consisting of (i) polyurethanes; (ii) polyacrylates and polymethacrylates; (iii) ethylene-vinyl acetates; (iv) polyvinyl acetates and also mixtures and combinations thereof, and has a weight-average molecular weight Mw in the range from 70,000 g/mol to 10,000,000 g/mol, andwherein the dispersion or solution further comprises at least one film-forming agent in an amount in the range from 0.001 to 6 wt. %, based on the dispersion or solution; and (b) thereafter, the edge band thus provided with the laser-activatable adhesive layer is mounted, with exposure to laser radiation, onto at least one narrow side of the workpiece, while being adhesively bonded durably to the at least one narrow side of the workpiece,
wherein the edge band, before it is provided with the dispersion or solution of the adhesive polymer, is provided with an adhesion promoter or is subjected to a surface-activation. |
