Cartax CXDP Powder

Fluorescent Pigment for Special Marking Applications

Cartax CXDP Powder is a specialty product having a pronounced fluorescent effect, for use in the printing inks industry. In normal daylight conditions, Cartax CXDP Powder is virtually invisible on paper. However, on exposure to UV-A light (optimal effect achieved at approx. 350 nm) the very distinct yellow-green fluorescence of high intensity becomes visible (emission at approx. 540 nm). Cartax CXDP Powder is thus a highly effective special additive for coding and marking purposes.
