Applications
Trigonox 178 is a convenient pre-blended initiator suitable for curing unsaturated polyester, vinyl ester and acrylic thermosetting resins at ambient conditions in conjunction with a metal salt. Trigonox 178 produces lower exotherms than standard MEKP’s and is useful in warm and hot weather climates. Applications include cast polymer and laminates.
Trigonox 178 is a slower reactivity MEKP/CHP blend for curing promoted unsaturated polyester matrices at room temperature used to suppress exotherm in thick or hot parts.
