The factors to be considered in selecting the optimum initiator / acclerator system are:
- Process
- Resin Type
- Required gel time or pot life
- Part thickness
- Room temperature
- Nature and quantity of additives
- Dosage optimisation between Sentinel Hardener and accelerator
Bullet GRP hardener is Methyl Ethyl Ketone Peroxide used for the cure of unsaturated polyester resins at room temperature in combination with a cobalt accelerator.
