What is AF Glass? Understanding Anti-Fingerprint Coating Glass Technology

AF Glass anti-fingerprint coated glass close-up showing optical clarity and coating quality

AF Glass, short for anti-fingerprint glass, refers to a type of coated glass that has a glass surface treatment that integrates a specific type of anti-fingerprint (AF) coating that does this to reduce smudging, improve optical transmittance, and protect the optical glass aesthetic. The anti-fingerprint coating creates a thin, uniform, chemically bonded layer on the glass surface, thereby lowering its surface energy, preventing finger oils and water-based smudges from adhering to it.

AF-coated glass repels oil (such as skin and other body oils) and water to some extent, which means it provides a more pleasant user experience due to its added smoothness and optical transmittance. Increased transmittance extends the lifespan of the glass's aesthetic qualities and improves the user experience (people enjoy using it more), making it better suited for touchscreens and glass coverings (for displays) that are used prominently.

AF Glass surface demonstrating lotus effect and hydrophobic anti-fingerprint properties

The science behind all of this is drawn from a particular phenomenon called the lotus effect. The AF coating alters the surface at the nanoscale to reduce the glass's surface area in contact with liquid. As a result, water beads and rolls off the surface, and skin oils (such as those from human contact) are repelled, making the glass much easier to touch. This works particularly well in situations where a glass pane is under heavy use (e.g., in kiosks, cars, and other industrial applications), helping it maintain optical clarity and resist glare.

Performance Metrics: Water Contact Angle on AF Glass
105° ± 5°

One benchmark for anti-fingerprint performance is the water contact angle, which is 105° ± 5° for Saiwei Glass products. This angle demonstrates strong hydrophobicity, causing water droplets to roll off the glass surface rather than spread. Consistent water contact angles on AF glass demonstrate the quality of the coating, in conjunction with AR coating stacks, to optimize light transmission, reduce glare, and provide cleanable, anti-fingerprint glass for a variety of applications.

Client — A Tier-1 automotive supplier developing infotainment systems for a leading Chinese EV brand
The supplier was sourcing a cover glass for a 15.6-inch EV dashboard touch panel that would serve as the vehicle's primary control interface. The glass needed to meet stringent automotive-grade standards — including thermal shock resistance from -40°C to 85°C, high surface hardness (≥9H), anti-fingerprint performance that endures constant driver interaction, and precise edge processing for seamless integration with a curved dashboard bezel. Previous AF coated glass samples from other manufacturers had failed the 1,000-hour damp heat reliability test.
AF Glass developed a purpose-built automotive display glass panel using 0.7mm chemically strengthened aluminosilicate glass with a nano-scale oleophobic coating optimized for high-temperature durability. Our engineering team ran extensive pre-production tests aligned with the AEC-Q200 standard and performed CNC precision cutting and 2.5D edge polishing to meet the exact curvature specifications. We also applied an AG (anti-glare) + AF coating combination to reduce dashboard reflections while maintaining the anti-smudge surface — solving both visibility and cleanliness in one integrated glass solution.

Client — A US-based industrial automation firm producing HMI (Human-Machine Interface) controllers for manufacturing plants
The client's HMI touchscreen panels were being operated by workers wearing oil-contaminated gloves in heavy manufacturing environments. The standard soda-lime cover glass they were using degraded quickly — the oleophobic coating wore off within months, and fingerprints and industrial grease made the interface nearly unreadable. They needed a durable industrial touchscreen glass panel OEM partner capable of delivering ruggedized glass with a long-lasting anti-fingerprint surface, custom silk-screen printing for the bezel area, and the ability to fulfill repeat orders of 500–2,000 pieces per batch with a 14-day turnaround.
AF Glass provided a complete custom cover glass manufacturing solution: 2.0mm chemically tempered glass with a hardened AF coating engineered to exceed 3,000 steel wool abrasion cycles (compared to the industry-standard 1,000 cycles). We used a vacuum evaporation coating process for uniform nano-scale oleophobic film deposition, followed by precision silk-screen printing with a customer-specified black border and logo. Our production team established a dedicated batch scheduling system to guarantee 14-day delivery on every repeat order — backed by real-time QC reporting shared via our customer portal.

Client — A North American smart home brand expanding into wall-mounted smart thermostats and control panels
The brand was launching a premium line of smart home glass panel thermostats with a 4.3-inch capacitive touchscreen. They needed a custom tempered glass cover that looked and felt premium — with an ultra-smooth anti-fingerprint surface, precise color matching for four different bezel colors (matte black, pearl white, champagne gold, and space gray), and a minimum order quantity low enough to support their initial launch of 5,000 units per SKU. Their previous supplier in Southeast Asia could not achieve consistent color matching across batches, leading to visible mismatches on retail shelves.
AF Glass offered a turnkey OEM/ODM custom glass panel service, starting with in-house color development and pantone-matched silk-screen ink formulation for all four colorways. We produced 0.55mm ultra-thin chemically strengthened cover glass with AF coating on the front surface for fingerprint resistance and an opaque decorative layer on the rear for the bezel design. Our MOQ flexibility (starting from 500 pieces per SKU for new product launches) allowed the client to test market response before committing to high-volume production. Every batch was validated through a Delta-E color consistency test to ensure uniformity.

Client — A major ATM and self-service terminal manufacturer deploying across Southeast Asian banking networks
The manufacturer needed a cover glass for ATM touchscreen panels that would be deployed in high-traffic public locations — from air-conditioned bank lobbies to outdoor semi-exposed kiosks. The glass had to combine three critical properties: anti-fingerprint performance to maintain readability after thousands of daily touches, vandal-proof impact resistance rated at IK10, and anti-glare treatment for sunlight readability. They also needed a reliable cover glass supplier in China capable of handling ongoing production volumes of 500–1,000 panels per month with consistent quality.
AF Glass engineered a triple-function cover glass solution: 3.0mm chemically strengthened soda-lime glass with an integrated AG+AF surface treatment — the AG (anti-glare) etching reduces reflectivity to below 1% for outdoor readability, while the AF (anti-fingerprint) top coat keeps the screen clean under heavy public use. We achieved IK10 impact resistance through a controlled chemical strengthening process that produces a compressive stress layer of over 250 MPa. All production batches undergo our 12-point incoming quality control protocol and are traceable via laser-engraved batch codes on every panel — meeting the client's supply chain traceability requirements.

Frequently Asked Questions (FAQs)

Antiglare and anti-reflective treatments are applied to reduce glare and improve visibility. When comparing AG to AF glass, the differences are primarily due to the AF layer's composition and the techniques used to apply the anti-reflective coating, such as multilayer dielectric stacks versus certain nanostructured surfaces. Both coating types aim to reduce glare; however, AF coating is specifically designed to improve the user experience of consumer electronics and industrial control panels by reducing surface reflections and enhancing contrast, thereby reducing glare.

Fingerprints are more difficult to leave on glass that is coated with an anti-fingerprint coating, which is usually applied on top of the anti-fingerprint glass, as the surface is less conducive to the adhesion of oils and water. Fingerprint-resistant coatings are incorporated into glass display products to keep the glass surface and viewing areas clean, especially in high-touch areas and consumer electronics such as smartwatches. This means that the combination of hydrophobic, oleophobic, and anti-fingerprint coatings provides durability and clarity in public spaces and consumer electronics.

Some properties of AF include fewer surface reflections, improved light transmission, and resistance to fingerprints and smudges. The AF coating reduces stray reflections, improving contrast and color fidelity by altering the refractive interface. Advanced technology enhances screen readability in bright light and improves the experience when using devices and flat-panel screens.

If comparing AG and anti-reflective glass, anti glare glass (AG) typically uses micro-roughened surfaces or matte finishes that scatter the surrounding light. This can cause a slight loss of sharpness. On the other hand, anti-reflective glass uses coatings engineered with thin-film interference to cancel reflections without scattering. In general, anti-reflective glass provides better sharpness and color fidelity, while AG glass is more suitable for high-glare environments. Hybrid glass products combine these methods to provide a balance of non-glare and optical clarity.

Use AR glass when maximum optical clarity and color fidelity are critical; anti-reflective coatings achieve this by applying thin-film layers tuned to specific wavelengths. The Electroplated AF process can produce durable, even anti-fingerprint coatings and can be combined with scratch-resistant coatings. For smart watches and other small consumer electronic devices, glass with both AF and anti-fingerprint technologies is used to enhance the durability and clarity, and to improve the user experience.

The glass surface is infused with a hydrophobic, oleophobic coating that causes water to bead and roll off, reducing streaks and smudging. The coating makes the glass surface easier to wipe and maintain, and the glass will have a cleaner, clearer appearance. When combined with an anti-reflective coating, the glass will have low reflections and be very easy to clean, making it a good choice for touch screens and displays visible to the public.

Industrial control panels typically use glass technologies to reduce reflections and absorb light. By minimizing the reflection of light from the glass due to the sun and overhead lights, critical information becomes more readable. Glass can also be treated as part of engineering glass that has AR coating and an anti-fingerprint coating, so that the glass can perform in functional glass surfaces in rugged environments. These choices of the glass products perform and ensure reliable operation and clarity, even to the control room operators under varying light conditions.

The lack of sharpness in the anti-glare glass is a negative perception. Recent advances in AR coatings and AG glass have improved focus and sharpness. The outer environments for glass products, including coated and uncoated glass, and the designed indoor lighting, are the controlled parameters. The absence of an anti-fingerprint coating and the stamped glass are the parameters that limit the contrast of the coated glass, thereby enhancing the durability and reflectivity of internal obstructions. The glass technology is current, and the selection of coatings is fitted for your intended purpose.
