Frequently Asked Questions (FAQ)
What are the main differences between the ST78, ST75, and ST70 smart film models?
The primary differences lie in color, TSER (Total Solar Energy Rejection), IR rejection, heat resistance, and substrate materials. ST78 offers the highest performance with 78% TSER, 95% IR rejection, and 120℃ temperature resistance using a Japan PET substrate. ST75 features 75% TSER and 92% IR rejection. ST70 is white, uses a South Korea PET substrate, and offers 70% TSER with 82% IR rejection.
How fast do these smart films switch between states?
All three models (ST78, ST75, and ST70) feature exceptional response times. They switch from the opaque (off) to clear (on) state in less than 45 milliseconds, and from clear (on) to opaque (off) in less than 200 milliseconds.
What are the UV and IR protection levels of the ST series?
The ST78 and ST75 models provide 100% UV protection and block 95% and 92% of Infrared (IR) rays respectively. The ST70 model blocks 99% of UV rays and 82% of IR rays, ensuring excellent thermal insulation and UV shielding.
What control methods are available for these smart films?
All models include One-Touch Control Button and Intelligent Light Sensing Control. The premium ST78 model additionally supports Program and mobile APP controls for smart home integration.
What is the working voltage and power safety standard?
The ST series smart films operate on a safe working voltage of 12V in the active (on) state, providing high energy efficiency and ensuring safety for residential and commercial installations.
How do the Visible Light Transmittance (VLT) rates compare when turned on and off?
When switched ON (clear), the ST78 and ST75 have a VLT of 88%, while the ST70 has 86%. When switched OFF (opaque), the ST78 and ST75 drop to 12% VLT for maximum privacy, whereas the ST70 drops to 14% VLT.
