Abstract: The aim of the invention is to increase the scratchproofness of a surface passivation, especially for fingerprint sensors. To this end, a sliding layer made of fat, oil, surfactants and/or wax is applied. Said layer reduces shearing forces. In a preferred embodiment, an emulsion made of water, paraffin oil, propyl glycol, lactarimic acid, cetylic acid, TEA, beeswax, carbomer 954, methylparaben, propylparaben and optionally perfume is used.

Abstract: To increase the scratch resistance of a surface passivation, in particular, for fingerprint sensors, a antifrictional layer is applied to reduce the shearing forces. The antifrictional layer includes fat, oil, surfactants and/or wax. The antifrictional layer is preferably an emulsion including water, paraffin oil, propylene glycol, stearic acid, palmitic acid, TEA, beeswax, carbormer 954, methylparaben, propylparaben and possibly perfume.
