This laser enhancement additive works by converting visible, UV or IR laser light energy into thermal energy, creating surface marks that contrast the color of resin material.
Cesa Laser Marking solutions not only contain a laser marking additive but also deliver a part’s color and can include other performance enhancing additives such as those for scratch or UV resistance.
