Process optimisation for primerless painting in motorcycle manufacture: Openair® Plasma for optimal paint adhesion and cool designs
Fibre-reinforced plastics are the main materials used in the manufacture of painted parts (such as cladding, tanks, fenders, etc.) In conventional processes, they are power washed and then flame-treated, followed by primering.
Using Openair® plasma significantly reduces the number of process steps. Precleaning is no longer required, and plasma pretreatment replaces flame treatment, and greater activation of surface tension is achieved without attacking the fibre structure. This means primer does not have to be applied either.
The result is a particularly stable paint adhesion and even colour finish. It has also been proven that pretreatment with Openair® Plasma significantly increases resistance to stone pitting on painted components.
