LUPEROX^® Z390

Luperox® Z390 is a peroxide blend used for the cure of unsaturated polyester resins in combination with a cobalt accelerator. At either room or elevated temperatures, Luperox® Z390 allows extremely fast curing, which means shorter cycle times and, as a consequence, higher productivity. Its formulation guarantees much better curing than normal acetyl acetone peroxide; this results in low residual styrene and tack-free surface GRP articles.
