PRODUCT BULLETIN OnColor™ Recovered Black OnColor™ Recovered Black is a black color concentrate that utilizes polymer material recyclate including pigments recovered from separate manufacturing processes. Used as a general purpose black, it is a versatile and cost-effective solution suitable for applications where a basic black colorant is required. An effective means of repurposing recyclate, OnColor R3 Recovered Black keeps waste from being sent to a landfill by reprocessing it into usable colorant.

Avient acquired the Clariant Color business on July 1, 2020 (the “Acquisition Date”). Design times can be less than three days for colorants. It’s in this spirit that we joined legacy PolyOne and the Clariant Color business, two complementary businesses, and formed a new one that we’ve named Avient.
