Accelerators are chemical substances which activate peroxides. Some of Poliya's resins and almost all gelcoats are preaccelerated and already include accelerators. Depending on the processing conditions, users must add accelerator into the gelcoat or resin and then, only after carefully mixing, should add peroxides. Most cobalt or amine based accelerators activate the peroxide at or below room temperature.

Organic peroxides are unstable products which may undergo self-accelerating decomposition. It is strongly recommended to store at under 25°C (or at specific temperature stated by peroxide producer), in a dark place. Keep peroxides away from accelerators and promoters.
Users should add accelerators and promoters into the resin first. Then, after thoroughly mixing, add peroxides into the system.
