Frequently Asked Questions
What are the key differences between the ST78, ST75, and ST70 smart film models?
The primary differences lie in their heat rejection performance (TSER), IR blocking capabilities, viewing angles, and maximum temperature limits. The ST78 model offers the highest specifications, featuring 78% TSER, 95% IR rejection, a wider 150° viewing angle, and heat resistance up to 120°C using premium Japan PET substrate. It also supports Program/APP control.
How fast do these smart films switch between states?
All three models (ST78, ST75, and ST70) feature rapid switching speeds. The transition time from off (opaque) to on (clear) is less than 45 milliseconds, while the on-to-off transition takes less than 200 milliseconds, ensuring near-instant privacy.
What is the operating voltage for these smart films?
The working voltage required when the film is switched to the "on" (clear) state is a safe low-voltage 12V. This ensures energy efficiency and safe daily operation in various environments.
How effective are these films at blocking harmful UV and IR rays?
These smart films offer exceptional UV and IR protection. The ST78 and ST75 models block 100% of UV rays and up to 95% and 92% of IR rays respectively. The ST70 model blocks 99% of UV rays and 82% of IR rays, significantly reducing heat and protecting interiors from fading.
What control methods are available for these smart films?
All models come equipped with a One-Touch Control Button and Intelligent Light Sensing Control. The premium ST78 model offers additional flexibility by supporting Program and mobile APP control integrations.
