| Résumé : |
Powder coatings can become more environmentally friendly if raw materials and production processes for the polyester are formulated without substances of very high concern (SVHC) in accordance with EU legislation (Reach Chemicals Ordinance). In addition, the content of monomers in resins and hardeners can be reduced through optimised production processes. With improved polyester resins, the powder coating manufacturer can formulate powder coatings that enable paint shops to handle powder coatings more safely. |
