Trigonox 21S, tert- butyI peroxy -2-ethylhexanoate, is a perester which is used for the curing of unsaturated polyester resin at elevated and high temperatures.
Trigonox 21S is preferred for the curing of UP resin based Hot Press Moulding formulation (such as SMC and BMC) in the temperature range of 120 - 160°C. As Trigonox 21S is a high reactive peroxide, it is very suitable as a kicker in formulations for pultrusion and SMC/BMC.
In combination with a cobalt accelerator, Trigonox 21S is also applicable for the cure of UP resins in the temperature range of 60°C and higher. Application area can be air drying lacquers, diplacquers, wall panels, filament winding, etc.
Trigonox 21S has normally a much shorter pot life in the pure resin than Trigonox C, tert-butyl peroxybenzoate.
