Trigonox 29-CL50

Thermoset composites

Detailed description

Trigonox® 29-CL50 is a 50% formulation of the perketale 1,1-Di(tert-butyl peroxy)cyclohexane in isododecane which is used for the curing of unsaturated polyester resins at elevated temperatures. Trigonox® 29-CL50 is preferred for the curing of UP resin based Hot Press Molding formulations (SMC, DMC, BMC etc.) in the temperature range of 120-170°C. Trigonox® 29-CL50 can also be used in combination with high reactive peroxides like Perkadox® 16 as kicker in formulations for pultrusion in the temperature range of 100-150°C. As Trigonox® 29-CL50 is a perketale, the stability of this peroxide in an UP resin is hardly influenced by the presence of metal accelerators, pigments or fillers. Trigonox® 29-CL50 is therefore very suitable for pigmented and non-pigmented Hot Press Molding formulations where a long shelf life of the compound is required. Trigonox® 29-CL50 is restricted applicable for Low Shrink and Low Profile formulations in view of possible surface imperfections.
