From Regulation to Reformulation: Gurit leads the way in safer epoxy chemistry for the wind sector

In 2024, the European Union chemical agency investigated 59 epoxy diluent chemicals and applied a CMR (carcinogenic, mutagenic, and reprotoxic) classification to them, which resulted in most two-component epoxy systems on the market also being reclassified. Supply chain communication of new classifications began this year, with harmonised classification expected to become legally binding for some substances from next year. 

Towards the end of last year, Gurit technical experts led the way with the development of patent-pending technology for true alternatives for the very small number of the reclassified chemicals that are used in the company’s products sold into the wind sector. The work has continued across Gurit’s epoxy formulated range, with alternatives now available for most of the affected Gurit products. Despite the regulatory approach only covering the EU, Gurit has decided to roll out the new formulations worldwide. Overall, the Gurit solutions have not affected cost or performance, a result which has been well received by customers, for whom it has been business-as-usual, with minimal impact on product qualification status.  

Gurit products for the wind sector, such as the Ampreg 32 (alternative to Ampreg 30) and Ampreg 33 (alternative to Ampreg 31) laminating systems, Spabond 730 adhesive, as well as an epoxy in mold gelcoat, meet the new CMR requirements and are available immediately.

Gurit’s response to the changes is aligned with the company’s global chemical safety strategy. The team continually monitors the regulatory landscape for early warnings of possible reclassifications and diligently works to reduce the number of substances of very high concern (SVHCs) used in formulations and at production sites. The situation remains dynamic with new reclassifications occurring every year, resulting in an ever-growing SVHC list. Chemical safety and product performance are always front-of-mind for the Gurit team.

By proactively testing, researching, and developing alternatives, Gurit ensures that wind blade manufacturers continue to access the safest and highest-performing epoxy products on the market.  

 About Gurit:

Gurit is a leading supplier of composite materials and solutions to wind blade factories and service technicians across the world, including epoxy hand-layup lamination systems, adhesives, and gelcoats. As the EU reclassified key epoxy diluents, Gurit’s technical team developed patent-pending alternatives for the wind energy sector. Products that meet new safety standards without compromising performance.
