Nouryon (formerly AkzoNobel Specialty Chemicals) will showcase Nouryact, a line of copper- and iron-based accelerators at JEC World in Paris, France, this week.
Due to a recent reclassification, there is an increasing interest in alternatives to accelerators that use cobalt-octoate.
They are used in combination with organic peroxide, accelerators cure unsaturated polyester and vinyl ester resins.
They are also used for the manufacturing of glass fibre-reinforced end products, including pipes, boats, gelcoats, food silos and storage tanks.
The copper Nouryact solution is suitable when curing temperatures range between 20 and 50 degrees, Celsius, and the iron-based variety is used mainly in higher curing temperatures.
“Through extensive trials and customer testing, the copper and iron versions of Nouryact have proven to meet the same performance standards of cobalt-based accelerators,” said Roel Zuijderduin, Polymer Chemistry Technical Development Manager at Nouryon.
“In fact, when curing vinyl ester resins or acrylic-modified styrene-free resins, Nouryact accelerators often offer better curing performance than the standard cobalt offering.”
