REACH restriction

New REACH restriction on diisocyanates

A new EU Regulation 2020/1149 entered into force the 24 August 2023. It restricts the use of diisocyanates and mixtures containing 0.1% by weight or more diisocyanates.

Diisocyanates are chemicals used in the production of polyurethanes and thus they can be found in small quantities as residual monomers in polyurethane coatings. As diisocyanates can trigger allergies, the EU Regulation 2020/1149 stipulates that after 24 August 2023, diisocyanates and mixtures containing >0.1% diisocyanates can only be used and processed if the user has successfully completed training on safe use of diisocyanates.

Who is in scope of the training

A person who uses products containing >0.1% diisocyanates in their business or as part of their commercial activities or who monitor the use of such products is in scope of the mandatory training. This applies to both employees and self-employed persons.

How to be trained

The European Diisocyanate and Polyol Producers Association (ISOPA) has in cooperation with the Association of European Aliphatic Isocyanate Producers (ALIPA developed a comprehensive training material that can be accessed cost-effectively. It’s easily accessible and available in several languages via and for various application sectors. The training must be renewed every five years.

Affected products

Below you can find both the list of our polyurethane products which do not require further training and the list of our polyurethane products, which do require training.

You can always consult either the product label or the product safety data sheet under section 15.1. If there is a text stating, As from 24 August 2023 adequate training is required before industrial or professional use . For two-component products, it is often the curing agent containing diisocyanate. All safety data sheets are available under the product search.

Fact box

Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) is a European Union regulation dated from December 2006. REACH addresses the production and use of chemical substances, and their potential impacts on both human health and the environment.

The regulation also established the European Chemicals Agency (ECHA), which manages the technical, scientific and administrative aspects of REACH.
