Measurement of the Adhesive Thickness on Glass by Beta Backscatter (CAT#: STEM-ST-0171-YJL)

Introduction

Few may be aware of this, but windshields and rear glass windows are simply glued onto automobiles. Maintaining the correct adhesion is critical because if the window is not bonded tightly enough to the car, a slight incident or shock could allow the window to fall off the vehicle. Also, if the windows are not correctly sealed to the vehicle, both water and air can penetrate the cabin. The amount of the adhesion and sealing is due in large part to the thickness of the adhesive primer coating. Beta backscatter systems are used extensively to closely monitor the primer thickness, ensuring that proper adhesion is appropriately maintained.
