The Wintech X200 series is a true carbon film that is color stable because it does not contain any dye. The densely packed nano-carbon compounds used in its construction give the film very high heat rejection and immunity against fading. The IR rejection is higher than standard low-reflective HP films at dark shades. Unlike HP films, the X200 series contains no metal and therefore will not interfere with signals. The X200 keeps the interior cool while providing a beautiful carbon black exterior that matches factory tint.
