The European Union has reclassified 59 epoxy diluent chemicals as CMR (carcinogenic, mutagenic, and reprotoxic), impacting most two-component epoxy systems on the market. This regulatory change prompted a wave of reformulation across the industry.

For the composites sector where epoxy systems form the backbone of structural laminates, prepregs, tooling resins, and high-performance bonding, the reclassification carries direct implications. Any shift in epoxy chemistry affects processing behavior, mechanical performance, certification protocols, and long-term durability across wind energy, marine, transportation, and industrial composites. As a result, suppliers have been under pressure to deliver safer formulations without disrupting composite manufacturing workflows.

The Gurit technical team has been developing products not classified as CMR for some time, and last year developed patent-pending alternatives for the small number of reclassified chemicals used in their products. These new solutions meet the latest safety standards without compromising performance or cost. The reformulation process has been extensive, but for customers, it s been business as usual with minimal impact on product qualification or supply.

Their approach is part of a broader chemical safety strategy, where they continually monitor regulations, reduce the use of Substances of Very High Concern (SVHCs), CMR and high hazard substances, and invest in ongoing research and development to stay ahead of future changes. The situation remains dynamic, with new reclassifications expected each year.

Gurit is committed to ensuring safer, high performing epoxy products are available to our customers.
