Overview

This course provides insight into key areas related to coloration of polymers — basics of color theory with some focus on color matching, classes of colorants, their chemistry and global sourcing, building of a robust colorant gamut and some issues related to coloration process. Weatherability and stabilization of color formulations will also be addressed.
