Film Characteristics

Excellent Adhesion

VDI 3198 Film Adhesion Test

PDLC film adhesion test result shows excellent bonding strength between film and base material, test result displays HF1 bonding strength

Lower Coefficient of Friction


PDLC film exhibits low coefficient of friction at 0.09. Lower COF contributes to slower wear and tear on sliding surface.

Diamond Bonding Structure

Raman Spectrum of PDLC Coating

Raman spectra with Gaussian peak fitting of ta-C coating. The spectrum consists of two peaks centered at 1330 cm_1 (D band) and 1548 cm_1 (G band) respectively. The Id/Ig ration is approximately 0.25. The broadening of the lines is attributed to an amorphous structure of the films.
