Failure of Foam Adhesive on Painted Side Panels - Surface Science Western

Request for analysis: Plastic mouldings are attached to painted surfaces of an automobile side panel using a foam adhesive strip. During application at an assembly facility it was noted that intermittent failures of the adhesive were occurring and, as time progressed, full failure of all mouldings were found. Objectives: Methodology: The foam adhesive surfaces, painted side panels exhibiting full failure and intermittent failure, as well as known good reference panels were analysed by X-ray...
