ECHA: Diisocyanates restricted under REACH

Diisocyanates should not be used on their own or as a constituent in other substances or in mixtures for industrial and professional uses in concentrations above 0.1 % by weight after 24 August 2023.

Placing on the market will be restricted earlier as of 24 February 2022.

Diisocyanates are respiratory and skin sensitisers. They are mainly used to make polyurethane products, such as foams, sealants and coatings.

Restricting their use is estimated to prevent over 3 000 new cases of occupational asthma per year in the EU.
