Yes, high-quality anti-fingerprint filmstill plays an effective role in the sunlight, the premise is it possesses suitable optical and surface properties. The performance of Mr.Film's anti-fingerprint film is affected by three key conditions : surface hydrophobicity/oleophobicity (which determines how oils behave on the surface), optical clarity and transmittance (which affects perceived visibility), and UV durability (which ensures long-term stability). Independent research performs that advanced anti-fingerprint film coating can keep over 95% excellent transparency while providing effective smudge resistance even in the complex sunlight conditions.
However, not all anti-fingerprint film are same. The function between sunlight, surface micro-structure, and fingerprint residue determines the user experience. This article will explain the technology principle and why Mr.Film anti-fingerprint technology can provide reliable performance in the bright environment.
Under sunlight or strong light environments, fingerprint are easier to be seen than indoor or under low-light conditions.
Research published in Progress in Organic Coatings confirms that fingerprint residue on untreated surfaces causes a significant reduction in optical performance, because the residue will change light transmission and surface reflection characteristics. The issue is particularly in the high translucent display screen and smooth surfaces, because every uneven surface can be saw under the oblique light conditions.
This is why even though the surface looks clean, unprocessed standard screens or shiny surfaces also exposed every touch immediately. The combination of high ambient illumination and uncontrolled oil spreading creates an unavoidable visual distraction.
Mr.Film's anti-fingerprint film incorporate advanced surfaces chemistry technology to change the mode of interaction between skin oil and the film. This technology is relies on oleophobic (oil-repelling) and hydrophobic (water-repelling) properties, which are achieved through specialized fluorinated or silicone-based polymer coatings.
The mechanism operates as follows:
①High contact angle: When the fingerprint oil contacts the surfaces, it will form a droplet shaped rather than spreading out and expand. Advanced fingerprint coating contact angle usually over 90% in the water and artificial fingerprint solution.
②Reduced surface contact area: Beaded oils have significantly less surface area in contact with the film, making them less visible and easier to wipe away.
③Controlled oil dispersion: Some advanced methods such as use the proprietary optical mechanism formula, disperse fingerprint oils into an ultra-thin layer that reduces light scattering to the maximum extent.
The key problem is whether this surface modification effect optical clarity, particularly under strong lighting.Peer-reviewed research provides clear answers:
①Transparency retention:Hybrid UV-curable anti-fingerprint coating materials have demonstrated excellent transparency of more than 95% transmittance, comparable to uncoated optical-grade substrates.
②Haze control: Quality anti-fingerprint films maintain low haze values, ensuring that diffused light scattering does not degrade image contrast or clarity.
③Anti-glare integration: For applications requiring both fingerprint resistance and glare reduction, advanced films combine surface texturing (for anti-glare) with oleophobic topcoats, achieving balanced performance without compromising either function.
Under direct sunlight, Mr. Film’s anti-fingerprint products exhibit three beneficial behaviors:
①Reduced fingerprint oil contrast: because fingerprint oils bead rather than spread, the refractive index difference between oil and air is less interference to light transmission. Smudges appear as faint, low-contrast marks rather than bright, glaring patterns.
②Uniform oil distribution: The oleophobic surfaces prevent the "oil" phenomenon for unprocessed glass, in which finger drag leaves visible streaks. This effect is particularly important under sunlight, because directional light will magnify the oil stain marks.
③Easy to clean under all conditions: Even after long-term use, just using soft cloth can wipe all stains without specialized cleaners required. The surface's functions are intact without leaving “ghost” residue that becomes visible under bright light.
A critical concern for any film exposed to sunlight is degradation of the anti-fingerprint coating due to UV radiation. Lower-quality coatings may lose their oleophobic properties over time, leading to progressively worse performance.
Mr. Film’s anti-fingerprint technology incorporates UV-stable siloxane-based polymers that maintain surface properties under extended sunlight exposure. Independent research on similar advanced coating systems has demonstrated:
①Permanent anti-fouling effects after UV curing, with no significant degradation of hydrophobic or oleophobic properties under accelerated aging tests
②High thermal stability alongside UV resistance, ensuring consistent performance across environmental conditions
③Cross-linked network durability that prevents the topcoat from wearing away with normal use
Q: Will Mr. Film anti-fingerprint film make fingerprints completely invisible under sunlight?
A: Every coating can make invisible completely under all conditions. However, Mr.Film's high-quality anti-fingerprint film reduces fingerprint visibility to an extremely low level, so that stains do not influence normal viewing effect even under direct sunlight. The oils bead up rather than smear, minimizing light scattering and contrast.
Q: Can I use glass cleaner on Mr. Film anti-fingerprint film?
A: Yes, please with caution. Use only ammonia-free, alcohol-diluted cleaners (maximum 50% isopropanol) as recommended by industry guidelines. Aviod using pastes, bleaches, or undiluted solvents. A dry or slightly wet microfiber cloth usually can achieve daily cleaning.
