AROL Anti Reflection Film
Optiguard™ AROL (Anti Reflection Optical Laminate)
Optiguard™ AROL has been specially developed by Panel Graphic to enable more products to benefit from an affordable AR coating solution. Exceptional light transmission and anti-reflective properties combined with excellent durability makes Optiguard™ AROL the ideal solution for a broad range of applications.
- NO minimum order quantities
- ANY custom sheet size – minimal waste
- ANY material
- ANY thickness
- ALL from stock ensuring short lead times
Anti Reflection Optical Lamination coating will dramatically reduce scratching when applied to acrylic or polycarbonate sheet giving surface hardness approaching that of glass together with superior resistance to chemical attack.
It is suitable for internal and external use but it is recommended that UV stable substrates be used when exposed in direct sunlight.
AROL Features
- Excellent transmission and overall visual performance achieved by utilising optically clear adhesive
- The hard coat layer gives high levels of abrasion resistance with the added benefit of fingerprint
resistance – also known as AFP or ETC - Excellent durability. Environmental exposure testing to ISO 16474-3 method A, including exposure
to 5% salt solution - Suitable for application via pressure lamination process to a wide range of substrates including
PMMA, Polycarbonate and Glass

Evaluation Method
- Drop each chemical on the AR film surface so that it has a diameter of 10mm
- After the stated time has passed, wipe off the chemicals with gauze
- Visually evaluate any changes in the AR film surface
