What is the response time for these smart films to switch states?
All models (ST78, ST75, and ST70) feature ultra-fast reaction times. The state switching response time is less than 45 milliseconds from off to on, and less than 200 milliseconds from on to off.
How do the UV and IR rejection properties compare across models?
The ST78 and ST75 models provide 100% UV rejection and up to 95% and 92% IR rejection respectively. The ST70 model offers 99% UV rejection and 82% IR rejection, ensuring excellent thermal protection and UV shielding.
What are the Visible Light Transmission (VLT) levels in the ON and OFF states?
When switched ON, the ST78 and ST75 models achieve 88% VLT, while the ST70 achieves 86%. In the OFF state, VLT drops to 12% for the ST78/ST75 and 14% for the ST70, providing optimal privacy.
What control methods are available for these smart films?
All models support One-Touch Control Button and Intelligent Light Sensing Control. The premium ST78 model also features advanced Program/APP control integration for smart home systems.
What is the difference in substrate materials and temperature resistance?
The ST78 and ST75 models use premium Japan PET substrate, resisting temperatures up to 120℃ and 100℃ respectively. The ST70 model utilizes South Korea PET substrate and resists temperatures up to 80℃.
