Titanium Nitride Film
Titanium nitride (TiN) film uses a thin sputtered TiN layer to reject heat and resist degradation; it is signal-friendlier than aluminium-metallised film but still contains metal.
Titanium nitride is a ceramic-like compound that behaves optically similarly to a metal but is more chemically stable and less prone to galvanic corrosion at the edges of the film. TiN films tend to have a slightly warm, bronze-gold appearance from outside.
Compared to aluminium-sputtered films, TiN attenuates signals less but is not as signal-clean as a true nano-ceramic.
TiN sees more use in architectural applications than automotive in the Singapore market. For cars, true ceramic and multi-layer optical films are the modern standard.
