3M™ Ultra-Clear Solar Film (UCSF) is a clear UV-blocking window film that rejects infrared (IR) light to help protect delicate electronics, head-up display (HUD) systems and picture generating units (PGUs), help increase passenger comfort and potentially decrease reliance on AC. A cooler cabin with less AC usage may lead to reduced fuel/charging costs, improved fuel efficiency/EV range fuel efficiency and decreased emissions. The non-metallic construction of this clear solar window film will not reduce electronic device signal strength or significantly alter the appearance of glass.
With design aesthetics trending towards larger panoramic glass roofs, seamless appearance and a modernized sleeker look, removal of the shark fin antenna has become more appealing. OEMs can now integrate antennas in a variety of places within the cabin without worrying about signal attenuation.
Complex glass curvatures present fabrication challenges when incorporating metalized coatings for solar control. 3M UCSF has properties that makes it conformable to complex and highly contoured surfaces, expanding the possibilities for glass designs needing solar control.
And with greater than 90% transmission of visible light with virtually no color, 3M UCSF provides outstanding visual clarity.
Passengers can enjoy an added level of comfort when their vehicle is shielded with 3M UCSF. A study conducted by 3M has shown a reduction in skin surface temperature that translates to a feeling sensation of up to 14°C / 25°F cooler.* The same study showed a 10% reduction in the power draw of the AC compressor and blower fan.
Passengers on a long road trip will appreciate the IR rejection properties of 3M UCSF when they sit inside a stationary car to wait for the battery recharge. Since the film reflects IR heat, the glass on the inside stays cooler to the touch. 3M UCSF becomes more effective as the sun changes position throughout the day and throughout the seasons. The more sunlight that hits glass at an angle, the more the film’s IR rejection capabilities increase.**
3M UCSF doesn’t contain metal which means minimal-to-zero EMI. Metallized window glass and laminate films designed to block solar irradiance exhibit signal attenuation and require removal of the metalized solution in specific areas where signal or camera-based systems operate — such as behind the rearview mirror — exposing these areas to increased solar load.
