Their high popularity is due to their fascinating interplay of color and to effects due to the various materials employed in their layered structures. Refractions and reflections of light at, and within, those layers cause interferences yielding selected colors.
Our May issue focuses on sustainability, specialty chemicals, automotive coatings and manufacturing equipment. This issue will also be distributed at the Eastern Coatings Show in Atlantic City, May 15-17, 2017.
