USE OF A LATENTLY REACTIVE ADHESIVE FILM FOR ADHESIVE BONDING OF ELOXATED ALUMINIUM TO PLASTIC

摘要

In order to bond the anodized aluminum to the plastic with an adhesive, it has a melting temperature T (melting) of 35 ° C ≤ T (melting) ≤ 90 ° C, especially 40 ° C ≤ T (melting) ≤ 60 ° C and is capable of reacting with isocyanate And one or more latently reactive adhesive film layers having an isocyanate-containing component dispersed in particulate form in the thermoplastic component and inherently inactive in the particle surface area, said particles having a viscosity of 40 0 (Initiation) ≥ 100 ° C, particularly 45 ° C ≤ T (initiation) ≤ 90 ° C, particularly preferably 45 ° C ≤ T (initiation) ≤ 75 ° C, to be. Laminates of anodized aluminum bearing the aforementioned adhesive products and plastics are used in particular in the electronics industry, for example in mobile phones or laptop computers.
