  • Applications

    Thermoset: Trigonox 141, 2,5-Dimethyl-2,5-di(2-ethylhexanoylperoxy)hexane, is a di-functional perester which is used for the curing of unsaturated polyester resins at high temperatures. Trigonox 141 is preferred for the curing of UP resin based Hot Press Molding formulations (such as DMC and BMC) in the temperature range of 120 - 160°C. Trigonox 141 is preferably used in combination with a low reactive peroxide like Trigonox C or Trigonox BPIC-C75 and an optimal low Profile SMC formulation for the production of HPM parts with a Class A surface at short molding times. Polymerization of styrene: In suspension polymerization processes, Trigonox 141 can be used for the polymerization of styrene at approximately 90°C. Trigonox 141 has an activity comparable with Dibenzoyl peroxide (Perkadox L-W75). However, the bifunctional Trigonox 141 gives higher molecular weights of the polymer. Applying the same molecular weights means a reduction of polymerization time. Polymerization of acrylates and methacrylates: Trigonox 141 can be used as initiator for the solution (co)polymerization of acrylates and methacrylates in the temperature range of 80-160°C, amongst others for the manufacture of coatings. Trigonox 141 can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methacrylates.
