  • Applications

    Perkadox CH-50 is a free flowing, fine, granular powder containing 50% dibenzoylperoxide for the curing of unsaturated polyester and acrylic resins at ambient and elevated temperatures. At temperatures up to 80°C, Perkadox CH-50 should be used in combination with an aromatic tertiary amine accelerator, above 80°C the use of an accelerator is not required. Perkadox CH-50 is easy to handle, easy to disperse and dissolves very quickly in unsaturated polyester resins and acrylic resins. When in acrylic resins a very high degree of transparency of the cured part is required the special grade Perkadox CH-50L is advised. The curing system Perkadox CH-50/amine accelerator shows a very fast cure that is hardly influenced by humidity and fillers. Even at low temperatures a relatively good cure will be obtained. A disadvantage may be the yellow color and poor light resistance of the moulded product.
