The European Chemicals Agency (ECHA) has opened a consultation on the inclusion of four substances of very high concern (SVHCs) in the REACH authorisation list. These substances, known for their hazardous properties, are widely used in various industries, including coatings, adhesives, and plastics. Stakeholders are encouraged to contribute feedback regarding socio-economic impact and potential alternatives before the consultation deadline.

The substances under review are as follows:

• Bumetrizole (UV-326): A UV stabiliser frequently used in coatings and plastics to enhance durability and protect against UV degradation.
• 2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol (UV-329): Another UV stabiliser with similar applications, playing a critical role in outdoor coatings and polymer protection.
• Triphenyl phosphate: A flame retardant and plasticiser commonly used in resins, adhesives, and coatings formulations.
• 2-(dimethylamino)-2-[4-methylphenyl)methyl]-1-[4-(morpholin-4-yl)phenyl]butan-1-one: A photoinitiator utilised in UV-curing applications for coatings and adhesives.

Implications for the coatings industry

The consultation is particularly relevant for the coatings and adhesives industry, where these substances are integral to high-performance formulations. If included in the authorisation list, companies will need to apply for continued use or find alternative materials that meet regulatory and performance requirements. This may result in increased costs and R&D efforts to identify substitutes.

ECHA aims to balance the risks these substances pose to human health and the environment with their socio-economic importance. The consultation period provides an opportunity for industry stakeholders to voice concerns and share insights into the challenges posed by substitution and regulatory compliance.
