| Résumé : |
Polymer adduct hardeners make it possible, even under REACH, to develop individual solutions and hus respond flexibly to customer requirements. This article describes the statutory rules laid down by the European Chemicals Agency (ECHA), approaches to such solutions and the results achieved. Polymer adeduct hardeners match the performance profile of conventionally produced adduct hardeners. |
