Liquid nano glass for phone. “Liquid protection” for smartphone screens: true or fake? Cases and real protective glass

For comparison: the thickness of conventional protective glass is 0.3 mm. The cured composition remains invisible for 365 days.

ProtectPax has a hardness of 9H, which is similar to ruby or sapphire crystal. The composition protects against mechanical damage, and also reduces the intensity of electromagnetic radiation for the user when using the device by 92.7% and neutralizes 99% of bacteria. It has oleophobic properties, prevents fingerprints and repels water.

ProtectPax improves shooting quality when applied to the glass protecting the camera. The composition also increases the sensitivity of the screen.

Applying the composition is much easier than gluing glass. You just need to clean the surface of the screen with napkins and distribute the composition. The developers promise that you will not see any air bubbles between the screen and the glass, or any loose edges. And if the glass needs to be selected for the smartphone model, then the liquid is suitable for any device.

10 minutes after application, you can hit the screen with a hammer and scratch it with various tools:

The miracle composition costs $15 (863 rubles) - about the same as protective glass for a smartphone in popular retail chains. 93% of the required amount has already been collected for the project, so there is no doubt about the success of the campaign - there is still a month until the end of the collection.

Expert opinion

Experts are not sure that ProtectPax can really 100% protect a smartphone from mechanical damage. Re-Mobile service center specialist Artem Anisimov notes that such trains are already available in Russia, their price is 300-1500 rubles. However, the compositions have more disadvantages than advantages:

“Firstly, it’s not as effective as they say. Customers still bring broken screens. Secondly, the liquid needs to be applied evenly, which is not possible for everyone. Thirdly, removing such protection from the screen is far from easy if you want to remove it get rid of it. Fourth: under warranty, your gadget is unlikely to be repaired after this liquid."

The expert also warned that such compounds are often counterfeited, so you should treat them with caution. At best, the smartphone will be left without protection; at worst, the screen can be completely damaged.

Scientist Oleg Mosenkov is also skeptical:

“I would not recommend such experiments. Do you seriously think that you will get a miracle composition for this money? It’s unlikely. Moreover, you are unlikely to throw scissors at your smartphone. And ordinary scratches will appear even with such protection. But I’m much more worried about safety precautions, because we hold a smartphone in our hands around the clock. I would like to see guarantees that this liquid is safe for the skin."

The biggest fear of every smartphone owner is display damage. This can happen even if you fall from a small height, and repairs will be expensive. A solution to this problem was proposed by young startupers from Düsseldorf.

The founders of the project, Pascal Buchen and Anthony Filipiak, claimed that they had created a protective liquid for the display, which protects the screens of phones and tablets not only from scratches, but also from severe damage. You just need to apply “liquid glass” containing nanoparticles to the screen, and after 12 hours of curing the material’s strength increases by 600%.

The young people presented their project called ProtectPax during a TV show, showing how it works in practice. Very impressively, they hit the treated surface of smartphone screens with a hammer, which withstood the force. And one of the investors was so impressed that he decided to invest €150,000 in the project, subject to receiving a 20 percent share from participation in the enterprise.

Perhaps he was too hasty with his investment. When the product hit the market in mid-October, there were reports of legal problems due to overly promising advertising. On this basis, the ProtectPax advertisement, which used the wording “100% protection against damage and scratches” on the packaging, as well as a symbolic picture where ProtectPax protects against hammer blows, was replaced with a more modest version - without a hammer and with the promise of “easy to use.”

Pseudo-discovery and fake evidence

There can be no talk of startups’ own discovery, since almost identical products have been on the market for several years: the first videos about similar protective coatings for displays appeared on YouTube back in 2012.

CHIP magazine even found one foreign entrepreneur who several years ago offered very similar protection for phones, but due to lack of success, turned to creating other products. He didn't want to be quoted by name, but during the conversation he confirmed what we suspected: the hammer blow demonstration on TV was most likely fake.

But does ProtectPax have any effect at all? We took this protection and three other products for comparison to the test center and studied everything down to the smallest detail.

For our test, we first used an iPad, half of whose display we covered with ProtectPax liquid exactly as directed, and left the other half untreated. After scratching with scissors and a knife, the first impression simply amazed us. The untreated side appeared less damaged than the one coated with ProtectPax.

Checking with a scraper and kitchen sponge

To eliminate any chance of chance, we treated four identical new smartphones with ProtectPax and three other competitor products in the same manner as the iPad. For the scratch test, we used a professional sclerometer, used to test varnishes for wear and scratch resistance.

The device is a 0.5 mm wide tungsten carbide nozzle, which, through a spring mechanism, presses with a certain force on the surface under test and scratches it. Our engineers installed eleven stages with a pressure force interval of 3–30 MPa and began to mock the displays. In addition, they rubbed the glass surface with sand and tried to find out what marks the pressure of 1.5 MPa, created by the rough side of a kitchen sponge, left on the display.

The result was completely different than we expected. None of the four smartphones showed any difference between the treated and untreated sides after the scratch test. The entire surface of the displays was damaged in the same way. No protective fluid delivers on its promise of keeping your display scratch-free. We, of course, refused to test with a hammer.

Cases and real protective glass

We do not exclude the possibility that the so-called “liquid glass” protects phone displays from daily damage, for example, from keys or coins in a trouser pocket. But it cannot offer effective protection against strong mechanical influences. We didn't do a drop test, but a thin protective film is unlikely to be a reliable means of preventing the display from cracking if you drop your smartphone.

Protection for curved displays: Precisely sized plastic or glass covers protect mobile phones with curved displays.

Professional cases: Cases such as the OtterBox Strada, although they cost about 3,000 rubles, protect smartphones well from strong mechanical influences.

That's why we suggest the following: Use proven scratch protection films. For smartphones with a flat display, this is the number one choice. For curved displays around the edges, the film may quickly begin to peel off, in which case transparent display covers are recommended. They are available for all common phone models.

It's better to pay a little more money for these covers made of glass or artificial materials, but buy good protection. As practice shows, cheap products spoil quickly. Shock-absorbing cases are suitable for preventing damage from falls: these devices with a protective coating protect the display well. Although they are, perhaps, powerless against the blows of a hammer.
