What to Use When the Adhesive of a Dash Cam No Longer Sticks?
1 Answers
If the adhesive of a dash cam no longer sticks, you can apply some water to the suction cup before attaching it to the windshield for a firmer hold. If it still doesn’t adhere, it is recommended to use 3M double-sided tape. Several factors affect adhesion, primarily including temperature, time, and pressure. Prolonged exposure to high temperatures can reduce adhesion, making it difficult to ensure the dash cam stays in place when the car is parked or not in use during hot weather. High temperatures cause the adhesive to decompose, releasing gas, while the expansion of gas between the adhesive and the material due to heat can counteract surface pressure. This is why adhesive failure and dash cams falling off frequently occur in hot weather. Before installing the dash cam, clean the installation area on the windshield thoroughly and use a hairdryer to warm the adhesive tape for better adhesion. Alternatively, you can opt for a rearview mirror-mounted dash cam, which can be secured onto the rearview mirror using clips or elastic straps. This method is simpler and more stable compared to suction cups or adhesive tapes.
