ICA CHINA dealers attended a refresher course on colorimetry, stains and special effects and excimer technology. From the theory and workflow of color, to the techniques of applying dyes on different substrates, then moving on to the formulation of metallic products and concluding with the presentation of excimer technology applied to the family of products in the Smatt line: an intense week that saw them involved in many application activities. We would like to thank Paolo Magnaterra for the excellent organization and CAO XI for the tireless translation that allowed an effective transmission of the many contents offered.
