Product Description: Norox? MEC FRED is a red blend of methyl ethyl ketone peroxide and cyclohexanone peroxide containing diluents. It is intended to be used as an initiator for unsaturated polyester resins and provides excellent curing properties at both low and ambient temperatures. The addition of a red dye aids in mixing and indicates that proper curing is complete when the color fades. TECHNICAL DATA: Reactive oxygen content not to exceed 9.0. Liquid in form, colorless. Specific gravity at 25°C is 1.12 and viscosity is 18.0 cps. Flash point is 170°F / 77°C (SETA C.C. method). Soluble in oxygenated

NOROX?MCP Chemical name: methyl ethyl ketone peroxide CAS No.: 1338-23-4

Product Description: NOROX? KPM is a colorless to slightly yellow liquid consisting of methyl ethyl ketone peroxide and acetyl ethyl ketone peroxide modified with dimethyl phthalate. Main applications: for curing of unsaturated polyester resins with cobalt accelerators at 20 - 40 °C. Particularly suitable for curing molded polyester parts at room temperature. Technical Data: Appearance: Transparent yellowish liquid Desensitizer: Dimethyl phthalate Active Oxygen (AO): min. 7.7% w/w Density (20 °C): approx. 1.13 g/cm3 Viscosity (20 °C): approx. 28 mPa ? s Flash

DESCRIPTION: NOROX? KP-9 FRED is a red colored flowable liquid consisting of a peroxide based on methyl ethyl ketone which is basically inhibited with phthalate plasticizers. This ketone peroxide is used as an initiator (free radical source) for curing unsaturated polyester resins. The main application is for curing glass fiber reinforced products at room temperature in combination with cobalt accelerators. This red colored version helps to control homogeneous mixing and changes color during the curing process. TECHNICAL DATA: Appearance: red transparent liquid Active Oxygen Content: 9.0 - 9.2% Free Hydrogen Peroxide Content: 1.6 - 1.8% Water Content:
