At room or elevated temperatures, AKPEROX ZZ 350 achieves extremely fast curing, which means shorter cycle times and thus increased productivity. Its formulation guarantees a better cure than common acetylacetone peroxides; this results in low residual styrene and non-tacky surface GRP products. The product has been specifically studied for continuous processes, such as continuous filament winding of GRP pipes. It is also suitable for centrifugal casting and sheet lamination.
