Specialists commend the black dots found on car windshields

as a remarkable technological advancement that plays a vital

role in the overall functionality, despite often being overlooked.

These dots form part of the frit band, a textured enamel paint strip

that encircles the perimeter of the windshield. This band is crucial for

enhancing the adhesion between the adhesive and glass, ensuring that the windshield is firmly secured to the vehicle.

The black dots not only act as structural components, but they also shield

the adhesive from potentially harmful UV rays. This safeguard prevents

the adhesive bond from deteriorating due to prolonged sun exposure.

The dot matrix, composed of increasingly smaller dots, aids in achieving uniform distribution of temperature throughout the windshield manufacturing process. This proactive measure prevents optical distortion or “lensing,” ensuring that the glass maintains straight lines accurately.

The gradual disappearance of the black dot matrix contributes to the aesthetically pleasing shift from the see-through glass to the black frit border. Additionally, this design choice enhances the structural strength of the windshield, decreasing the risk of damage.
