CATALYST & PEROXYDES

Peroxides are essential for catalyzing the curing of polyester and vinylester resins, playing a crucial role in the fabrication of composite parts. The selection of the appropriate catalyst depends on several reactivity criteria, including the expected gel time, exothermic peak temperature, the time required to reach this peak temperature, and ultimately, the final curing of the parts. These factors are critical to ensuring efficient manufacturing processes and optimal performance of the cured composites.
