Product Description: NOROX® MCP-75 is a solution of methyl ethyl ketone peroxide and isopropyl phenyl hydroperoxide. Liquid polymerization initiator specifically designed for curing unsaturated polyester and vinyl ester resins at room temperature. Characterized by low exothermic peaks, longer gel times, excellent final cure and avoidance of in-plant mixed peroxides. Has very low levels of impurities including water, hydrogen peroxide and butanone. Typical Properties: Reactive Oxygen: 9.0%, Max Form: Liquid Color: Pale Yellow Specific Gravity: 1.10 (25°C) Flash Point (SETA C.C.): 150°F (66°C), Min Soluble in oxidizing organic

Product Description: Product Name: NOROX® MEKP-925H Chemical Composition: Methyl ethyl ketone peroxide Physical State: Liquid Mixture Product Characteristics: Specifically formulated to reduce outgassing in vinyl acid resins for critical corrosion prevention applications such as gelatin coatings, barrier coatings and corrosion resistant structures. Low hydroperoxide levels often require modification of the resin promotion system to obtain reasonable gel times. TECHNICAL DATA: Reactive Oxygen Content: not more than 9.01 TP6T Form: Liquid Color: Colorless and Clear Specific Gravity (25°C): 1.10 Flash Point (C.O.C.): not less than 200°F Flash Point (SETA C.C.)
