Induction heating has had good acceptance in bonding applications where metal substrates are involved. With metal bonding, the substrate is heated by the electromagnetic field generated by a current passing through an induction coil. Heating to cure temperatures occurs within fractions of a second and temperatures can easily surpass the limits of any organic adhesive. Other advantages of induction heating are low energy consumption, safety for operators, and no direct contact with the substrate surface. In this study, thermoplastic polyurethane (TPU) adhesives were synthesized from aromatic diisocyanate, polyester polyol and diol by bulk polymerization without volatile solvent. The effects of metal powder content on the adhesion, melt viscosity, melt index, mechanical properties and inductive heating properties of metal/TPU adhesives were investigated. |
