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

摘要

To adhesively bond eloxated aluminium to plastic a product having at least one layer of a latently reactive adhesive film which has a thermoplastic component which has a melting point T(melting) such that 35°C = T(melting) = 90°C in particular 40°C = T(melting) = 60°C and contains functional groups which can react with isocyanate and an isocyanate containing component which is dispersed in particulate form in the thermoplastic component and is essentially deactivated in the region of the particle surface where the particles have a start temperature T(start) such that 40°C = T(start) =100°C in particular 45°C = T(start) = 90°C particularly preferably 45°C =T(start) = 75°C; where T(start) = T(melting) is used. Laminates of eloxated aluminium with the abovementioned adhesive product and plastic are employed in particular in the electronics industry e.g. in mobile telephones or laptop computers.
