Again, the oleophobic coating saves electronics from "obesity"

Great achievements in the field of microelectronics, especially intense in the last decade, began to arouse in people an ever greater desire for comfortable surroundings with amazing things. Aesthetics and power intertwined in the ephemeral manifestation of the human mind - the world was shown a multi-functional phone with a touch-sensitive control panel, the screen of which received an oleophobic coating. The amazing substance and ingenious simplicity of the invention will be discussed in the framework of this article.

A bit of biology and a little bit about physics

It is one of the features of human physiology that served as a kind of impetus for using a substance whose properties would prevent the appearance of fat traces on the surface of the touchscreen. After all, it's not a secret for anyone that a smooth base, moreover, possessing certain mirror properties, is incredibly fancy material. Oleophobic coating solved all the problems. The touch screen has acquired a fairly serious defender, which can easily save aesthetic beauty and effective practicality of color display.

The "heroine" of the narrative is "Mrs. Chemistry"

So, what is an oleophobic coating and what are the components of the "miracle" substance? In order not to introduce into the terminology, let's say only that it is a certain substance based on: alkylsilane (organic hydrotrioxide), silicone - polyorganosiloxane polymers (silicone) and solvent (as a binding element). However, a film only a few nanometers in thickness can effectively reflect multiple "tactile attacks" of fingers of our hands. That is, the above spraying serves as a natural barrier to fat in any of its manifestations. By the way, the chemical composition of the human fingerprint is nothing more than an aggressive environment, which has in its composition a fairly serious arsenal of various substances: several kinds of acids, ammonia, salt and phosphates. So sweaty hands - "stress" for oleophobic coating. At the same time, everything has its limits, and the protective properties of sputtering are not an exception to the rules. However, about this in the next paragraph.

What kills the oleophobic coating?

The main cause of the destruction of the protective layer, of course, is considered to be a mechanical effect. And the intensity of use of the device, which has a spraying of "anti-fats", is far from being a creative force. Nevertheless, all the above-described reasons are "nothing" compared to aggressive environments, which often become "saviors" in the hands of a person who is thoughtlessly trying to wipe an ink spot from the touch screen of a cheap device. Practice shows that at first glance, "innocent substances" sold under the guise of a "superfood" effectively cleans the oleophobic coating of the screen from any contamination, in fact, dangerous liquids containing alcohol or its derivatives or various solvents. Only after some time the owner of the phone or tablet will pay attention to the fact that fingerprints have become "with progressive strength" to be fixed on the touch screen of your favorite device. And yet for those whose experience was "unsweetened," there is a way out.

Non-production spraying, or Deceive yourself (Chinese reductant)

Information in the network on a given topic is more than enough. Imitating the protective layer of substances on the market today there is an incredible amount. For your information, even an expensive can of can not guarantee the factory quality (often promised in the annotation to the product), and even more so the durability of the layer obtained as a result of sputtering, rubbing or digging. At best, you will get a matte fog on the glass or you will achieve a grease repellent protection with a daily duration. Common sense should make you doubt the "miracle recipe", and life experience - require a detailed study of the issue: oleophobic coating - what is it? Dear readers, do not be deceived, because the technology of applying a protective layer is a complex chemical process of a production type. By the way, not every patent is publicized (referring to the improved type of spraying from Apple). Agree - this example is worthy of reflection. However, as promised, an effective way still exists.

Simple, fast, reliable and cheap

The protective film, of course, will not save your device from "signs of individuality" (fingerprints), but its application will certainly favorably affect the presentable state of the face of the device. In any case, wipe the display you can safely damage the oleophobic coating. A quality film will protect your touchscreen from scratches and abrasions, and a small price of an accessory will not become an obstacle to re-making a replacement for the damage protection element. It should be noted that many manufacturers have long mastered the technology of applying a grease-repellent composition to polymer products. So for owners who lost the factory protective layer, and those people whose electronic units were not originally "oleophobes", such an alternative is really an ideal option to significantly affect the degree of security of the device, as well as to increase the level of comfort when using it.

Summing up

As you understand, an oleophobic covering with your own hands can be unconsciously destroyed, but now you know that there are some opportunities for restoring the protective layer. So do not be discouraged if in past tense you have committed an operational error ... Alas, this is how a person is created, although it is much more painless to learn from other people's flaws. Be wise and protect your device from "obesity."
