Marine AR PMMA


Special and tough environment attacks coating layers on display a lot.  With this anti salt water AR coated, the surface will not easy to get damaged, and still keep the high transparence as originally.  
Protector for marine displays was the original idea of this development. 

After multiple layers coated, total transparence within view area still keeps 98% above.

Product Structure


1. Solid Anti Salt Water AR coating protects the vapor deposited layers away from peeling off within tough operation surroundings.
2. High transparence, low reflection for both sides.
3. Optical grade PMMA with vapor deposited coating in 1 or 2-side.
4. 440~640nm reflection under 0.5 %
5. 300~700nm reflection under 2%
6. Total transparence above 98% within whole view area
7. Dirt, finger print easy remove
8. Anti Smudge coating makes water contact angle above 110-degree.
9. Anti Scratch, abrasion resistance.
