Peroxyde, accelerators & inhibitors

We offer you a comprehensive selection of organic peroxides/inhibitors and accelerators. They are usually used as hardeners for unsaturated polyester resins. The production of high-quality laminates requires that resins and hardeners are optimally coordinated under consideration of the processing method. Please contact us - we will be glad to assist you!
