Characterization and quality assurance of surface preparation on plastic parts

With the aim of increasing wetting, adhesion, and long-term stability usually surface pretreatments are carried out on plastic surfaces for subsequent painting and bonding processes. Depending on the treatment methods, materials and subsequent processing steps, a variety of characterization methods are available. An overview is given of established characterization options for activated plastic surfaces, which are suitable for adjusting processes or quality assurance. In addition, new promising research approaches for two-dimensional and non-destructive quality control of activated plastic surfaces are discussed.
