Applications
Trigonox 21LS is a perester formulation based on tert-butylperoxy-2-ethylhexanoate, which is used for the curing of unsaturated polyester resin at elevated temperatures. Trigonox 21LS is preferred for the curing of UP resin based Hot Press Moulding formulations (SMC, DMC, BMC, etc) in the temperature range of 120 - 160°C. As Trigonox 21LS is a high reactive peroxide, it is very suitable as a kicker in formulations for pultrusion and SMC/BMC in combination with peroxides like Trigonox C and Trigonox 29-B50. Trigonox 21LS gives in comparison with Trigonox 21 a long shelf life stability of the compound, without affecting the cure speed, even when iron oxides or carbon black are used as pigment.
