tert-Butyl peroxy-2-ethylhexanoate

 

Trigonox® 21LS is a peroxide formulation used for curing unsaturated polyester resins at elevated and high temperatures.

CAS Number 3006-82-4

Trigonox® 21LS is a peroxide formulation used for curing unsaturated polyester resins at elevated and high temperatures.

Chemical Family Organic peroxide

Physical Form Liquid

Brand Trigonox®

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.

Molecular Weight 216.3

Concentration 6.44-6.69
