To eliminate buckling in sunroof panel during production, rolled pieces of butyl were used between roof bows and the outer skin to provide support. However, that product was labor intensive to use and challenging to consistently apply, which led to visible low spots in sheet metal on both sides of the sunroof panel and thus warranty concerns. To eliminate the buckling, specially formulated, cross-linked, autoclave cured PA 6 closed-cell foam was developed for use with butyl adhesive. The material survives e-coat and paint-oven temps, is lightweight, cost competitive, improves NVH, and saves $1 USD/vehicle vs. butyl rolls.
