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:

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
