AF vs AG vs AR Glass — Complete Comparison
Compare Anti-Fingerprint, Anti-Glare, and Anti-Reflective glass coatings with real industry data. Find the right surface treatment for your application.
💧 AF Glass
Anti-Fingerprint
Oleophobic & Hydrophobic Nano-Coating
A fluorosilane-based nano-layer (5–20 nm) that repels oils and water from touch surfaces. The coating lowers surface energy so fingerprints bead up and wipe away effortlessly.
Water Contact Angle≥ 110°
Light Transmittance≥ 92%
Steel Wool Test3,000+ cycles
Pencil Hardness4H – 6H
Glare ReductionMinimal
🌫️ AG Glass
Anti-Glare
Chemical Etch & Matte Surface Treatment
Chemical etching or spray-coated silica particles create a micro-textured surface (Ra 0.5–3.0 μm) that scatters reflected light, drastically reducing glare in bright environments.
Gloss Reduction80–120 GU
Light Transmittance≥ 88%
Surface Roughness0.5–3.0 μm
Pencil Hardness6H – 7H
Fingerprint ResistanceModerate
✨ AR Glass
Anti-Reflective
Multi-Layer Magnetron Sputtered Coating
4–8 alternating thin-film layers of TiO₂, SiO₂, and MgF₂ deposited via magnetron sputtering cancel surface reflections through destructive interference, maximizing clarity.
Surface Reflectance≤ 0.5%
Light Transmittance≥ 97%
Coating Layers4–8 layers
Pencil Hardness5H – 7H
Fingerprint ResistancePoor
