Process optimization for primerless painting in motorcycle manufacture: Openair® Plasma for optimal paint adhesion and cool designs
Fiber-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.
Long-term paint adhesion on motorcycle componentsUsing
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 fiber structure. This means primer does not have to be
applied either.
The
result is a particularly stable paint adhesion and even color finish.
It has also been proven that pretreatment with Openair® Plasma
significantly increases resistance to stone pitting on painted
components.
