In smartphones with a waterfall screen, flat glass does not provide adequate protection, and glass with curved edges is difficult to install. UV glass allows solving the problem of screen protection and the complexity of installation. The article will let you know what is UV glass and what are the features of the protective coating.

What is UV glass?

UV glass is a common name for protective coatings with an ultraviolet hardener. This method of fixing is used mainly with glass curved at the edges. The adhesive base under the action of an ultraviolet lamp hardens and forms a strong connection of the protective glass with the smartphone.

Features of UV glass

The protective coating is usually made of heat-or chemical-treated tempered glass. To enhance the strength characteristics, polymers are used as a base or additives, for example, as in Nillkin AP+ glass. The thickness of the protective coating is usually 0.33 mm, since 0.5 mm often does not provide a noticeable increase in strength. There is also an oleophobic coating to reduce the contamination of the coating. Glass of a transparent type and with a frame around the circumference are produced.

To fix the glass on the smartphone, a UV lamp is included. Most manufacturers put an ordinary lamp, which you need to hold with your hand over the screen. Just as often there is no USB cable in the kit, which is why you need to use the cable and charger that comes with the smartphone.

A thoughtful approach is used by Whitestone Dome company. In addition to the cable and lamp, the kit includes a matrix for installing and fixing the phone. And the presence of legs eliminates the need to hold the lamp in your hands and simplifies the process of installing glass. At the same time, Whitestone Dome products are more expensive than competitors.

  13. This completes the installation stage.

How do you remove UV glue from tempered glass?

To remove any glue residue, you need to pry a thin card of paper or plastic under the glass. Once you have peeled off the glass from the edge, gently continue to peel it further by pushing the plastic card between the glass and the screen. If the glass does not come off well, you should warm the glass with a hair dryer for 5-10 seconds. Remove the glass slowly, gently and carefully so as not to break it. After you have removed the glass, soak a cloth in isopropyl alcohol or use an alcohol wipe to wipe off any glue residue.
