Our Wet AR anti-reflective coating is a cost-effective alternative to vacuum-deposited anti-reflection solutions.
This option has exact color reproduction and is easy to clean. Furthermore, it has excellent chemical and wear- and abrasion resistance.
The abovementioned features make Wet AR an excellent choice for many applications, such as information displays or displays in public environments.
This is because Wet AR’s chemical- and abrasion resistance makes it suitable for surfaces regularly cleaned with harsh chemicals.
Lastly, it is worth mentioning that Wet AR can be designed in larger formats than solutions like Marine AR but with similar optical properties.
