The glass filler normally used to repair chips and scratches in automotive safety glass does not adhere to surfaces that have been treated with rain repellant. The goal of this research is to find the cause of the prevented adhesion of the glass filler. Representative automotive safety glass samples, along with the inner polymer layer, have been analyzed using X-Ray Photoelectron Spectroscopy (XPS) in order to examine the surface of these materials. The interaction between the rain repellant and the polymer layer are expected to show the cause of the lack of adhesive attractions between the glass filler and the problem area. The development of a solution to remove this problematic surface treatment is anticipated.
