Sealing a car windshield properly is important to ensure a long-lasting and strong bond. The automotive industry commonly uses two products for this purpose: automotive polyurethane sealants and adhesives. A proper seal for automotive windshields is crucial for both OEM installations and aftermarket repairs. It significantly impacts safety and longevity.

      Here is a detailed breakdown of the process along with two recommended products suitable for most automotive aftermarket windshield repairs. These products are both black-primer-free, maintain bead consistency upon extrusion, resist stringing, and offer easy application.

     1. OEM Installation:

Manufacturers meticulously prepare the surfaces by thoroughly cleaning them to ensure no dust or debris remains. A specially designed adhesive is applied to guarantee a flawless bond between the windshield and the vehicle body. Precise application is essential for a secure bond. After installation, the windshield is kept secure until the adhesive cures completely. It then undergoes inspection to ensure a firm fixation without any leaks.

     2. Aftermarket Repair:

Thoroughly clean the windshield and surrounding areas to eliminate any dirt or residue. Using the recommended adhesive gun, extrude the adhesive evenly along the windshield's edges, ensuring uniform coverage. Carefully place the windshield on the surface, ensuring complete contact between the edges and the adhesive, eliminating any air gaps. Employ glass clamps or other fixing methods to maintain stability during the curing process. Wait for the adhesive to cure completely before inspection.
