Product Description: Product Name: NOROX? ENP-90 FRED Chemical Composition: Methyl ethyl ketone peroxide (MEKP) Appearance: Red, flowing liquid containing a methyl ethyl ketone based peroxide, desensitized by means of a fatty ester. This ketone peroxide is used as initiator (free radical source) in the curing of unsaturated polyester resins. Special advantage: Due to the red peroxide, homogenization in the resin can be controlled and the red color disappears after curing. Highly efficient in special pre-accelerated and stabilized resin types. Main applications: Curing of molded parts at room temperature together with cobalt accelerators. Technical Data: Appearance: Red Liquid Active Oxygen

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:
