Products for Security Taggants & Markers (Ink)


Keystone offers several product lines which can enhance ink formulations by adding a layer of either overt or covert security.  One area is optical brighteners where they can be used as an indicator for the printing industry or even roof and tank liner coatings.

Other technologies like our Reversacol'sTM which are UV activated photochromic dyes are solvent soluble dyes that change from colorless to colored when activated by UV light energy and then revert back to colorless.  KeyfluorTM optical brighteners and invisible fluorescent dyes have no visible color but will fluoresce when exposed to UV light.  Keystone has many solvent soluble dyes also, like our Keyfast SpiritTM dyes, that can be utilized in formulations where only by exposure to solvents can they be detected.
