Keystone is a leading supplier of colorants to the vast and varied markets. Keystone Aniline Corporation offers many types of Security Tags, Taggants and Markers for use in Polymers and Plastic applications. Product Identity fraud (PIF) is a general term encompassing alteration, counterfeiting and diversion of raw materials and finished goods. One way to secure products against PIF is to include Security Marking and Security Tagging systems into the manufactured goods and raw materials. Often these Security systems are incorporated directly into the polymers, as valid systems for use in Plastics and Polymers.
