Session 4: Advancements in Automotive Finishing
There has been a developing trend towards electro-colored black finishes. Although electro-coloring has been the process of choice for the architectural industry, automotive requirements are more stringent and require different process technology. This presentation will be beneficial to designers, specifiers and applicators.
Light Materials – Treatments Optimizing Performance
Electro-coloring processes have been widely used in the architectural industry for many decades. This process of choice exhibits unsurpassed lightfastness for exterior applications and offers a range of colors that can be achieved. By varying the metal ions of the electro-coloring process, color tones from stainless steel, light to dark bronze, copper and true blacks can be achieved. Although these processes seem to be well understood, the finish requirements in the automotive industry are different and continuously changing. High gloss surfaces and pH resistant finishes have been becoming the norm for the automotive industry and pose challenges for applicators.
This presentation will illustrate the various influence factors on color tones and gloss levels of the final finish. It will demonstrate how quality consistency is achievable by optimizing pretreatment, anodizing, electro-coloring and sealing parameters. Besides the traditional silver and black finishes, newly developed electro-coloring process can extend the range of lightfast colors for exterior automotive applications and provide additional design opportunities.
