- Used as a curing agent for unsaturated polyester resins; may be used in combination with cobalt accelerators.
- Temperature range: 70°C to 150°C
- Usage level: 1–2%, may be used in combination with 0.5–1% cobalt accelerator.
- The “pot life” (gel time of resin + peroxide) can last for several weeks at room temperature (depending on resin type, fillers, and pigments).
- "Pot life" (gel time of resin + peroxide + accelerator) can last for several days (depending on temperature and peroxide level).
- Adding 0.1–0.3% of Inhibitor BC-500 can significantly extend the shelf life or pot life.
- Half-life: 10 hours/1 hour/1 minute (benzene, 0.1 mol/L): 74°C/92°C/130°C
