The function of black spots on the windshield that must be known
the function of the black line on the car window
Until now there are still many people who do not understand the function of the black line found on the car window. In addition to having a plain shape, the black line is usually also equipped with small spots. These spots and black color are known as frits. Frit has an important role in the windshield system of the car.
Frit is a very crucial part in the process of installing the windshield to the car body. In his explanation, a website mentions that Frit serves as the key to how the windshield can stick to the car body. Dedona, an automotive company engaged in various fields including US window film, explained that glass is a material that is difficult to paste with other materials. The surface is not easy to stick to the iron layer on the car body frame.
To overcome this, the frit is heated so that it can attach the windshield to the car body. This process also includes black spots that surround it. The main function of the frit is to provide a surface that makes the adhesive stick well to the glass. When the windshield will be installed, the frit acts as a meeting point between the glass and the frame. The surface of the frit helps the adhesive stick to stick effectively so that the glass and frame can blend perfectly.
In addition to assisting in the installation process, frit also functions as a protector of ultraviolet radiation. The outside of the frit protects the adhesive from direct sunlight. If exposed to sunlight continuously, the adhesive will weaken and potentially cause the windshield to come off on its own.
Visual effects and additional functions
The effect of spots that shrinks inwards gives the impression of a more attractive transition from the black frit frame to the transparent windshield. Although only a little, the spots also function as a barrier to sunlight. In appearance, the frit also hides the adhesive that is used to install the windshield well, giving it a smoother and neater look.
The effect of dissolving or shrinkage of black dots provides a more attractive visual transition from the frit black border to a transparent glass. In addition, this effect also helps in heat dissipation on a small scale. Thus, the frit not only serves as a structural element, but also as an important aesthetic and functional component on the windshield of the car.
