QWhat are the main differences between the ST78, ST75, and ST70 models?
The main differences lie in their performance metrics (TSER, IR, and UV rejection), viewing angles, heat resistance, and substrate materials. ST78 offers the highest specs with 78% TSER, 95% IR rejection, a 150° viewing angle, and Japan PET substrate, along with additional Program/APP control options.
QHow fast do these smart films switch between states?
All three models (ST78, ST75, and ST70) feature an ultra-fast response time, switching from off to on in less than 45 milliseconds, and from on to off in less than 200 milliseconds.
QWhat is the UV and IR rejection performance of these films?
ST78 and ST75 block 100% of UV rays, while ST70 blocks 99%. For Infrared (IR) rejection, ST78 blocks 95%, ST75 blocks 92%, and ST70 blocks 82%, providing excellent thermal insulation.
QWhat control systems are built into these products?
All models include a One-Touch Control Button and Intelligent Light Sensing Control. The premium ST78 model additionally supports Program/APP control for advanced smart home integration.
QWhat are the temperature resistance and substrate materials used?
ST78 and ST75 utilize Japan PET substrates, resisting high temperatures up to 120℃ and 100℃ respectively. ST70 uses South Korea PET substrate with a high temperature resistance of up to 80℃.
QWhat is the working voltage and thickness for installation?
All three models share the exact same physical thickness of 11mil and operate safely at a working voltage of 12V when switched on.
