Market Segments

Thermoset composites

Detailed description

Trigonox® 29-C75 is a highly efficient midrange initiator for curing unsaturated polyester and vinyl ester resins at elevated temperatures. Typical applications include prepreg, premix, BMC, TMC, SMC and pultrusion. Trigonox® 29-C75 is stable in the presence of pigments, especially carbon black, and provides excellent catalyzed shelf-life in BMC and SMC formulations.
