Composition - Property Relationships of Magnetic Inks for Screen Printing

Abstract:

Magnetic cards are widely used as credit cards, gift cards and VIP cards. In many industries, the principal method for producing the magnetic stripe still employs magnetic tapes. Therefore, if magnetic inks could be printed directly on the poly (vinyl chloride) (PVC) cards, then there would be the potential to improve industrial efficiency significantly. In order to apply the magnetic inks to the credit cards or other PVC cards, the Screen printing technique was chosen as a suitable printing method.In formulation 19, it is easy to mix and disperse the iron oxide powders in binder, few agglomerates and agglomerates occurred in the dispersion and also the film thickness of this formulation is around 20 microns which is ideal for the magnetic stripe.
