Over the past 20 years, automotive window film technology has not changed, yet today’s vehicles are equipped with state-of-the-art electronics and digital gadgets. SolarFree wants you to experience nanotechnology at its finest with ZTOA, a superior modern automotive film that rejects up to 95% of infrared heat while retaining the benefits of standard solar control film. ZTOA allows zero signal interference, 99% UV rejection, and blocks up to 59% total solar energy so that everyday drivers can remain cool even during the hottest summer days. ZTOA’s impressive ability lies in its highly developed construction, where superior-grade PET film meets advanced nanotechnology.
