The European Union has already required several changes to SDSs under both the chemical registration framework of REACH, and the Classification Labeling and Packaging (CLP) which result in similar format changes to those required under GHS. Q11: Carbon Black and Titanium Dioxide (TiO2) show up as carcinogenic hazards on some of our SDSs, and not on others. Therefore, they recommend a non-carcinogenic classification of these materials under GHS.

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.

We have negotiated 80 MWh of vPPAs across our North American and European operations. The cost of traditional energy to power 80 MWh is approximately $12,000. Requesting member Stanley Black & Decker, Inc.
