United Initiators NOROX®ENP-102 FRED Methyl ethyl ketone peroxide 1338-23-4

Product Description.

• NOROX® ENP-102 FRED is a red liquid consisting of a peroxide based on methyl ethyl ketone, desensitized by a saturated fatty ester.
• It is used as a source of free radicals to initiate unsaturated polyester and vinyl ester resins.
• The red color of the peroxide helps to ensure optimal homogenization of the mixture and the red color is no longer visible after the curing reaction.
• Primary application: Curing of large molded parts at room temperature with cobalt catalysts.

Technical data.

• Appearance: red liquid
• Active Oxygen Content: approx. 8.6% w/w
• Desensitizer: saturated fatty ester
• 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/vinyl ester resins

Applications.

• The primary use is for curing large molded parts at room temperature with a cobalt catalyst.
• Suitable for all unsaturated polyester resin types and vinyl ester resins.
• Standard dosage levels: 1-31 TP3T as supplied, 0.5-21 TP3T with 11 TP3T cobalt solution (or alternative cobalt amine catalyst).
• The curing time is short, especially when curing ortho-phenol or iso-phenol resins, which have relatively long curing times.
