Butanox® M-50 product is commonly used for room temperature cure of unsaturated polyester and vinylester resins and is always used in combination with a metal accelerator, often cobalt, like for example our Accelerator™ NL-49PN product which is a 1% cobalt solution. Cobalt carboxylates however are subject to ECHA reclassification and may become a SVHC in due course.
Nouryon already has a cobalt-free accelerator portfolio for years commercially available under Nouryact® brand.
This portfolio has been thoroughly tested and proven suitable for use in combination with our organic peroxides for room temperature cure of all standard available UP/VE and also the styrene free and acrylic modified hybrid resins.
Nouryact cobalt-free accelerators are for direct use in a standard cure system as replacement for the cobalt you are presently using. In case you need more freedom to formulate your resins to a cobalt-free resin there is the option to use the underlying technology for making cobalt-free resins. The BluCure® technology is licensed out to resin manufacturers to enable them to formulate their resins to a cobalt-free resin with the maximum degree of freedom to formulate the reactivity and stability. The BluCure® seal is an additional option for labelling your end product and clearly mark it as cobalt-free.
If you are interested in the Nouryact® cobalt-free accelerators or in the BluCure® cobalt-free resin technology, please contact us using the forms below or your local Nouryon account manager for additional information.
