Non-glare coating A3, i.e. MAT FINISH like on ANTIFLEX®-AR3, but with additional hard coating on both surfaces to increase scratch resistance (surface hardness of 6-8 H – pencil hardness – compared to 2-3 H of uncoated acrylic).
The test for surface hardness defined by ttv will irreparably damage any other plastic filter but leaves ANTIFLEX®-AR3/2h undamaged: sliding a weight (diameter 40 mm) of 250p – with a pad of steel wool #1 underneath – 3 times across the surface will not cause any visible scratches.
Improved chemical resistance protects the material not only from damages caused by oil, grease, or acids, but also prevents substances as aggressive as acetone from harming the surface.
Vast areas of application open up for this light-weight, hard to break ANTIFLEX®-AR3/2h because of its optical quality (gloss < 55%, haze < 2%, transmission 91%) well above industry standard for etched glass windows, and its flexibility in tint matching to enhance contrast.
