On 4 August, the European Union published the REACH Restriction on diisocyanates which will introduce mandatory training requirements for workers using diisocyanates from 24 August 2023.

To help stakeholders understand the next steps, ISOPA and ALIPA are now publishing an updated version of their e-book on the Restriction aiming to provide a brief introduction and answer some of the main questions that actors along the polyurethanes value chain may have.

The e-book is available for download here.  

In addition to the introduction provided by the e-book, ISOPA/ALIPA are committed to provide more information and answer questions from stakeholders moving forward.
