- A colorless, free-flowing liquid containing a methyl ethyl ketone-based peroxide that has been de-sensitized with phthalate plasticizers.
- The product is suitable for curing unsaturated polyester and vinyl ester resins at room temperature in combination with cobalt accelerators.
- Oxygen content: minimum 9.5%.
- Density: approximately 1.148 g/cm³; viscosity: approximately 23 mPa·s.
- Primarily used as a curing agent for unsaturated polyester and vinyl ester resins.
- When used in combination with a cobalt accelerator at room temperature, the recommended dosage is 1–3% of the resin weight.
- The “pot life” is typically only a few hours, depending on temperature and resin type.
- The “pot life” is relatively short, particularly when used with phthalate resins, but can be extended by adding inhibitors.
- When used with vinyl ester (VE) resins, it provides shorter gel and cure times compared to Curox M-200 or Curox M-300.
- Suitable for polyester resins, it provides longer gel and cure times.
- Heat generation during curing is moderate, resulting in lower internal stresses during the curing process.
- Relatively short demolding time, i.e., good demolding properties.
- Particularly suitable for hand lay-up, spray-up, centrifugal casting, filament winding, resin casting, and surface coatings (fillers, putty, adhesive layers, and topcoats).
- Use the spraying equipment in accordance with the manufacturer’s instructions.
- Ensure that all safety devices are functioning properly.
- Do not clean the spray tip by spraying methyl ethyl ketone peroxide into the air.
- Store the product in a sealed container at a temperature below +30°C.
- Keep in a well-ventilated area.
- Keep away from ignition sources and heat sources (e.g., direct sunlight).
- Isolate from other hazardous and incompatible substances.
- Avoid contact with skin, eyes, and clothing.
- Ensure adequate ventilation.
- If necessary, collect vapors at the point of generation using a dust collector.
- Avoid the formation of aerosols.
- Do not inhale vapors or aerosols.
- If necessary, wear appropriate respiratory protection.
