  • Applications

    Polymerization of (meth)acrylates: Trigonox 121 can be used to initiate the (co)polymerization of acrylates and methacrylates in the temperature range between 70°C and 120°C. Trigonox 121 can be applied in suspension as well as in solvent and bulk polymerization. Thermoset: Trigonox 121, tert-amyl peroxy-2-ethylhexanoate, is a perester which is used for the curing of unsaturated polyester resins at high temperatures. Trigonox 121 is preferred for the curing of UP resin based Hot Press Moulding formulations (such as DMC and BMC) in the temperature range of 120-160°C as such or as a kicker in combination with a low reactive peroxide like e. g. Trigonox C or Trigonox 127. The low reactive peroxide must be included in the formulation in order to achieve a complete cure.
