What Is Oleophobic Phone Screen Coating?

First thing’s first, "oleophobic" refers to a type of material that repels oils. This means that it can keep smudges off of any smooth surface, especially glass panels. Smartphone manufacturers started playing with the material in order to prevent grease from users’ fingers from creating annoying smears on their phone screens. While oleophobic coating makes your phone in no way immune to fingerprints, it does make it easy for you to wipe smudges off of it by simply using a soft, lint-free cloth.

Oleophobic coatings on gadgets make them feel slick to the touch, which helps in reducing friction and keeping scratches at bay. Unfortunately, the oleophobic coating wears off with time, depending on four things: Smartphone usage, user sweat acidity, polymer type, and polymer bonding procedure. Under perfect conditions, your phone’s oleophobic coating should last just as long as your phone does, which is a good two years (probably more). However, poor polymer quality, bad conditions, and misuse can contribute to your coating wearing out within months.

So, how do you know if your phone’s oleophobic coating has worn off, or if it even had one in the first place? In times of doubt, turn off your phone and drip water on its entire screen. If the water droplets form tiny spheres, the oleophobic coating is still in good condition. If they merely plop all over the display, then it’s high time to reapply another layer of anti-grease coating.

There are plenty of cheap oleophobic coating kits in the market today. However, none of them quite measure up to the ones in the slightly high-price range. High-end products are not only oleophobic, but also host other incredible features, including level 9 sapphire hardness, premium impact protection, and antimicrobial properties.
