MsbLongDescription
Trigonox® 42S, tert-butylperoxy-3,5,5-trimethylhexanoate, is a perester which is used for the curing of unsaturated polyester resins at elevated temperatures. Trigonox® 42S is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, DMC, BMC etc.) in the temperature range of 120 - 170°C. In combination with a cobalt accelerator (e.g. Accelerator NL-53N, 10% cobalt) Trigonox® 42S 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. Trigonox® 42S has in comparison with Trigonox® C, tert-butylperbenzoate, a somewhat higher reactivity in the pure resin as well as in HPM formulations.
