What kind of adhesive is used to bond car bumpers?
1 Answers
Structural adhesive is used to bond car bumpers. The bumper is a safety device that absorbs and mitigates external impacts, protecting the front and rear of the vehicle body. It consists of an outer panel, cushioning material, and a crossbeam. The outer panel and cushioning material are made of plastic, while the crossbeam is formed by stamping cold-rolled thin plates (approximately 1.5 mm thick) into a U-shaped channel. The outer panel and cushioning material are attached to the crossbeam, which is connected to the frame longitudinal beam with screws and can be easily detached. Methods for repairing bumper scratches include: 1. Apply toothpaste to shallow scratches and wipe counterclockwise with a soft cloth; 2. Spray car paint scratch repair agent onto the scratches and wipe with a towel; 3. Use a touch-up pen to spray and fill the damaged area along the direction of the scratch, then apply fine wax after it dries.
