    In 2014, a large manufacturer of automotive exteriors and interiors encountered a problem consistently adhering paint to their dashboards due to an inappropriate use of their flame treatment.

    Flame treatment is a popular and notable procedure that can successfully modify the surface chemistry of a polymer, readying it for adhesion. Although flame treatment is an effective solution, determining the amount of treatment can be a delicate procedure. The over-flaming of these highly sensitive polymers can lead to polymer reorientation due to localized melting and ultimately, destruction of the surface.

    In this case, however, the manufacturer was not utilizing flame treatment to monitor their surface cleanliness. Instead, they used it to deflash excess material on the edges of their dash boards. The edges of the dashboard were being over-flamed, hindering the polymer’s surface adhesion ability. This, in turn restricted paint from correctly adhering to the edges of the dashboard. The company needed a way to determine the appropriate amount of flame treatment.
