- NOROX® ENP-102 FRED is a red liquid consisting of a methyl ethyl ketone-based peroxide that has been deactivated with saturated fatty esters.
- It serves as a free-radical source for initiating the curing of unsaturated polyester resins and vinyl ester resins.
- The red color of the peroxide helps ensure optimal homogenization of the mixture; after the curing reaction, the red color is no longer visible.
- Main Applications: Curing large molded parts at room temperature in conjunction with a cobalt catalyst.
- Appearance: Red liquid
- Active oxygen content: approx. 8.6% w/w
- Desensitizer: Saturated fatty esters
- Density at 20°C: approx. 1.01 g/cm³
- Viscosity at 20°C: approx. 13 mPa·s
- Solubility: Insoluble in water; soluble in esters, unsaturated polyester resins, and vinyl ester resins
- Primarily used at room temperature in conjunction with a cobalt catalyst for curing large molded parts.
- Suitable for all types of unsaturated polyester resins and vinyl ester resins.
- Standard dosage range: 1–3% as supplied; 0.5–2% when used with a 1% cobalt solution (or an alternative cobalt amine catalyst).
- Curing time is short; however, it is relatively long, particularly when curing ortho-cresol or isocresol resins.
