Natural light is the best illumination for art galleries and museums, but the UV rays and heat it carries are also the primary causes of fading and deterioration in paintings and cultural relics. Although traditional curtains provide shade, they block out the light entirely, making it impossible to complement the lighting and shadow layout inside the exhibition hall.
Difei EPC smart tint film is specially designed for these light-sensitive spaces. Unlike traditional PDLC film, which only turns hazy and white, EPC delivers true tinting-changing only the light and dark states without compromising clarity.
When exposed to intense sunlight, it takes just two seconds to switch from fully transparent to a deep dark state. It blocks 99% of UV and IR rays as well as most solar radiation, protecting precious cultural relics from fading under the sun. Meanwhile, even when switched to its darkest state, the glass remains highly clear and transparent, with absolutely no impact on the view.
With a 2-second transition between light and dark, the tint film filters harsh sunlight into soft natural light. This perfectly restores the truest colors and textures of the artwork, allowing cultural relics to be preserved for the long term under safe natural light.
