Have you ever wondered about those tiny black dots on the edge of your windshield? Or the black border that runs around it? These seemingly insignificant details actually serve crucial purposes in the construction and functionality of your car’s vital window.
The Black Dots: Frit
Those small, black specks on your windshield’s edge are called frit. While they may seem like an aesthetic choice, they serve a critical function in the manufacturing process.
- Adhesion Enhancement: Frit creates a rough texture on the glass surface, improving the adhesive bond between the windshield and the car’s body. This ensures the windshield stays securely in place, even under extreme conditions.
- UV Protection: The black color of the frit helps to block harmful ultraviolet (UV) rays from reaching the adhesive, preventing it from deteriorating and weakening over time.
- Heat Distribution: Frit contributes to even heat distribution across the windshield, reducing the risk of stress cracks caused by temperature fluctuations.
