H1: Anti‑Fingerprint AF Coating for Sapphire｜Reliable Anti‑Smudge Vacuum‑Coating for Touch‑Surface OEM Hardware
H2: Introduction to Sapphire AF Anti‑Fingerprint Coating Touch‑facing sapphire components deployed within smartwatches, smart bands and medical endoscopes frequently accumulate fingerprints, sweat and oil‑based stains. Anti‑fingerprint coated waterproof sapphire cover for touch‑operated wearable display modules addresses these challenges via lotus‑effect nanoscale hydrophobic‑oleophobic surface layers.
Anti‑fingerprint (AF) coated scratch‑resistant sapphire crystal for consumer wearable device covers and anti‑smudge AF‑coated sapphire display window resisting oil stain for wearable touch‑screen devices form low‑surface‑energy nano‑coatings across polished sapphire surfaces, enabling easy removal of surface contaminants.
Original Daikin and Shin‑Etsu raw materials imported from Japan are utilized for AF coating processing. Production relies on South Korean Han‑I HVC 1600 vacuum coating machines, paired with US Veeco hollow‑cathode ion sources. All AF coating procedures take place within Class‑1000 dust‑free clean‑room workshops.
H2: Measurable AF‑Coating Durability Performance Data AF‑coated sapphire substrates pass rigorous steel‑wool abrasion testing executed under 1 kg pressure: ‑ Initial water contact angle ≥115° ‑ 3000 cycles: water contact angle ≥110° ‑ 5000 cycles: water contact angle ≥107° ‑ 8000 cycles: water contact angle ≥105° ‑ 10000 cycles: water contact angle ≥104° ‑ 15000 cycles: water contact angle ≥100°
Following heavy‑load long‑cycle abrasion, AF layers retain stable hydrophobic‑oleophobic performance, making them suitable for long‑lifespan consumer‑facing and industrial touch‑interface products. Test laboratories are fitted with water‑contact‑angle testers, pencil‑hardness testers and abrasion‑resistance test benches to deliver comprehensive quality inspection.
H2: Application Scenarios for AF‑Coated Sapphire ‑ Consumer wearables: smart‑watch crystals, smart‑ring cover plates, fitness‑tracker smart‑band touch windows ‑ AR‑MR hardware: touch‑operated AR‑glasses optical covers ‑ Medical optics: endoscope protective windows ‑ Custom large‑size touch‑panel sapphire covers
H2: FAQ Q1: What raw materials are used for Sun Yin Crystal AF coating? A1: High‑performance Daikin and Shin‑Etsu AF coating precursors imported from Japan are deployed, alongside Han‑I vacuum coating equipment with Veeco ion‑source assistance.
Q2: How durable is Sun Yin Crystal’s sapphire AF coating under abrasion tests? A2: Initial water‑contact angle reaches ≥115°. After 15 000‑cycle 1 kg steel‑wool friction testing, water‑contact angle remains ≥100°.
Q3: Can AF coating work together with AR anti‑reflection coating? A3: Yes. The AR film is deposited first, with an AF functional layer overlaid on top to deliver both high transmittance and anti‑smudge performance.
H2: Request AF‑Coating OEM Service Standalone AF coating and AR‑AF dual‑coating services are available for customer‑supplied sapphire substrates or internally manufactured sapphire substrates. Project specifications may be submitted to obtain sampling support and formal quotation.
