Thermoset composites
Curing systems for unsaturated polyester, vinylester and (meth)acrylate resins
We offer the world's largest range of curing agents for unsaturated polyester resins, vinyl ester resins and (meth)acrylate resins.
Our products shape the world around us. We understand the future needs of the unsaturated polyester resin composite industry and are committed to helping you further improve your curing systems. We offer a full portfolio of high-quality organic peroxides and auxiliaries. Accompanied with safety support and technical support to help you improve the composite end products you manufacture. Innovation and sustainability is in the heart of our activities, we hereto also offer phthalate-free and cobalt-free cure systems for all thermoset applications.
Product categories
We supply complex-based metal accelerators, which offer additional benefits including enhanced curing of VE resins and a strong reduction in gel time drift. These can also be used for curing (meth)acrylate resins and provide an alternative to benzoyl peroxide/amine curing systems. Amine accelerators are most commonly used in combination with benzoyl peroxide for curing all standard thermoset resins.
Our Nouryact® cobalt cobalt-free accelerators are based on Copper, Manganese and Iron and can be used as alternatives for conventional cobalt-based accelerators, while maintaining existing cycle times and mechanical properties.
The reactivity of cobalt-based accelerators can be increased by using Promotor™ C or Promotor™ D products. These promoters increase reactivity in curing systems, allowing for shorter gel time and faster curing for unsaturated polyester (UP) resins and vinyl ester (VE) resins when using ketone peroxide/cobalt accelerator or peroxyester/cobalt accelerator combinations at both ambient and elevated temperature.
In certain geographical regions, we supply a number of inhibitors for processing UP, VE and (meth)acrylate resins. Inhibitors act as radical scavengers and are used to extend the gel time and pot life of curing systems.
