  • Applications

    Perkadox BTW-50 is a paste containing 50% dibenzoyl peroxide without phthalate for the curing of unsaturated polyester resins at ambient and elevated temperatures. At temperatures up to 80°C, Perkadox BTW-50 should be used in combination with an aromatic tertiary amine accelerator, above 80°C the use of an accelerator is not required. Perkadox BTW-50 has primarily been developed for the putty market. For non filled systems, Perkadox CH 50X or Perkadox 40E are better applicable with respect to miscibility with the UP resin. Perkadox BTW-50 shows a very good chemical and physical stability and is therefore very suitable for tube filling. The curing system Perkadox BTW-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.
