Accelerators
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.

Cobalt Based Accelerators
Cobalt based accelerators activate peroxides at or above room temperature. Metal content of cobalt based accelerators are generally 1%, 6%, 8% or 10%. Cobalt metal concentrations are also available. Accelerator amounts depend on resin type, temperature and production method. It is recommended to use ratios stated on TDS in applications.

Packaging: 4 kg Mini Canister, 24 kg Canister


Amine Accelerator (Dimethylaniline)
DMA (Dimethylaniline) is the recommended accelerator in benzoyl peroxide (BPO) curing systems. BPO-DMA system offers fast gel and cure times at room temperature. It is not recommended to use DMA in UV resistant applications because of deteriorating yellowing resistance. DMA also offers fast cure especially at lower temperatures in Co-Mek-P systems. It is strongly recommended to test the additive in the laboratory before production.
