Flame Treatment is a method of chemically changing the surface molecular structure of a substrate in a controlled manner to:
> Increase 'Surface Energy' > Increase 'Wettability', and therefore compatibility with coatings and materials
Flame treatment can be applied to any olefin based plastic or metallic component, like bumper fascias, body side moldings, wheel covers, air spoilers, air scoops, door handles, door panels, consoles, dashboards, post trims, and carpet backing. Flame treatment is particularly applied when pre-treating plastic surfaces to enable printing, varnishing, coating, lining, gluing, foaming or floccation. The effectiveness of the gas flame is achieved, more than by the heat, by the provision of electrons and ions, which causes the oxidation of the surface molecules that allow the adherence of molecules of paint, dyes, glues, etc…
Flaming may be built into the line or included in the production logistics process without any need for storage
Due to the technological developments of recent years in gas flaming treatment units, a level has been reached which, today more than ever, presents flaming treatment as the best alternative for pre-treating plastics to enhance their adhering properties.
