AkzoNobel has extended its portfolio of Cobalt-free curing solutions with the launch of its second generation Nouryact accelerators.
Primarily based on Iron, the new eco-premium accelerators work in a wide range of temperatures and have a low colour impact on the end products. They are an easy to use replacement for existing cobalt-based accelerators and in some cases even outperform cobalt, enabling curing behavior which cannot be achieved with conventional systems.
End users can now select from six different Nouryact accelerators which can be combined with the full range of AkzoNobel’s peroxide curing agents, offering a Cobalt-free curing system for virtually every application. Nouryact accelerators are BluCure products and are 100% Cobalt-free.
Cobalt carboxylates like cobalt-2-ethylhexanoate are under evaluation by the European Chemical Agency (ECHA). In fact, some of them have already been classified as CMR2 Reprotoxic by the Cobalt REACH consortium under European Union’s CLP regulation. The evaluation process by ECHA is not yet closed and further reclassification -to carcinogenic class 1B- might take place.
