Anti-fog stickers are composed of nano-water-absorbent material and are known as physical anti-fog stickers. The anti-fog effect is always present, and most anti-fog stickers on the market are coatings. However, the coating will eventually wear out, causing the anti-fog effect to diminish over time.
There are two types of anti-fog sheets, one is a pure transparent color, and the other is photochromic. The principle of color change is that when there is no sunlight, it is transparent, and when there is sunlight, it automatically turns blue-black.
Available in color-changing and transparent colors
