EINECS/ELINCS No: 210 382-2

Applications: Polymerization of styrene: Trigonox C may be used for the (co)polymerization of styrene in the temperature range of 100- 140°C. In practice, combinations of two or more peroxides with diverging activities are used to reduce the residual monomer content in the final polymer and to increase reactor efficiency. Polymerization of ethylene: Trigonox C is an efficient initiator for the ethylene polymerization at high pressure in both autoclave and tubular processes. To obtain a wide spectrum of polymerization temperatures, Trigonox C is often used in combination with other peroxides. Depending on reaction conditions, Trigonox C is active in the temperature range of 220-270°C. Polymerization of acrylates and methacrylates: Trigonox C may be used as an initiator for the bulk, suspension and solution (co)polymerization of acrylates and methacrylates in the temperature range of 90-130°C. For Thermoset: Trigonox C, tert-butyl peroxybenzoate, is an aromatic perester, which is used for the curing of unsaturated polyester resins at elevated temperatures. Trigonox C is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, BMC etc.) in the temperature range of 120-170°C. Trigonox C can also be used in combination with high reactive peroxides like Perkadox 16 or Trigonox HMa as kicker in formulations for pultrusion in the temperature range of 100-150°C. In combination with a cobalt accelerator (e.g. Accelerator NL-53N, 10% cobalt), Trigonox C is also applicable for the cure of UP resins in the temperature range of 70°C and higher. Application area can be: air drying lacquers, diplacquers, filament winding, etc. For Crosslinking: Trigonox C is a monofunctional peroxide which is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Safe processing temperature: 100°C (rheometer ts2 > 20 min.). Typical crosslinking temperature: 140°C (rheometer t90 about 12 min.).
