Why Car Windows Have Little Black Dots ?
If you’ve ever looked closely at your car windows, you may have noticed small black dots scattered around the edges. These little dots are not just a decorative feature; they actually serve an important purpose in ensuring the safety and longevity of your car’s windshield.
So, why do car windows have these little black dots? Let’s take a closer look.
The black dots you see on your car windows are actually called “frits.” Frits are made of tiny ceramic particles that are baked into the glass during the manufacturing process. The purpose of these frits is to provide a smooth transition between the glass and the adhesive used to bond the windshield to the car.
Without these frits, the adhesive used to bond the windshield to the car would be more likely to crack or fail over time. This could lead to a dangerous situation, as the windshield could potentially come loose during a collision or other high-impact event.
In addition to providing a smooth transition for the adhesive, the frits also help to conceal the edges of the adhesive from view. This gives the windshield a cleaner, more seamless appearance.
Another benefit of the frits is that they help to block UV rays from the sun. UV rays can cause damage to the adhesive used to bond the windshield to the car, as well as to the interior of the car itself. By blocking these harmful rays, the frits help to extend the life of both the adhesive and the interior of the car.
Finally, the frits also serve as a visual cue to help drivers see where the windshield ends and the car’s body begins. This can be especially helpful when driving in rainy or snowy conditions, as it can be difficult to see where the windshield ends without these visual cues.
In summary, the little black dots you see on your car windows are not just a decorative feature; they serve an important purpose in ensuring the safety and longevity of your car’s windshield. So, the next time you’re driving down the road, take a moment to appreciate the frits and all they do to keep you safe and comfortable behind the wheel.
