Quantitative test method for evaluation of anti-fingerprint property of coated surfaces

▶ Artificial fingerprint liquid is formulated from PDMS, MP and artificial sweat. ▶ Direct determination of anti-fingerprint property of a coated surface can be made. ▶ Test method is confirmed by correlating to actual human fingerprints. ▶ Anti-fingerprint property can be achieved on smooth and optically clear surfaces.
