We specifically designed this anti-reflective coating for marine applications to ensure lifetime durability in offshore environments.
The Marine AR coating reduces light reflections to an absolute minimum and has exceptional UV- and saltwater resistance.
We typically recommend this solution for radars, fish finders, plotters, and navigation and communication systems exposed to saltwater and sunlight.
If you’re looking for an anti-reflective coating like Marine AR, but that is a more general-purpose solution, Wet AR could be an excellent option.
Like Marine AR, it has great chemical and abrasion resistance, except it’s a more cost-effective option if you’re not looking for an AR surface treatment specialized for marine- and offshore environments. Click here to read more about Wet AR.
