Cetox 50S is a peroxide initiator for copolymerization of unsaturated resins polyester. It is mainly used with cobalt accelerators at temperature surroundings. Suitable for manual and spray lamination. In relation to the hardener Cetox-50 shows a shorter gelation time, while compared to the Metox-50 initiator, gives a lower exotherm and a more gradual cure. Can be used also in technologies related to the production of thick laminate layers and for button production.
