Park Aerospace Nelcote® E-765 Epoxy Prepreg, T700 Uni Tape Reinforced
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Nelcote® E-765 is a tough 250°F cure prepreg system designed to replace 350°F cure systems in aircraft structural applications. FAA-approved Design Allowable Databases are available upon request. Key Features and Benefits: Designed to replace first generation 350°F (176°C) cure systems. Wide cure temperature process window of 250°F to 350°F Exhibits very low void content, i.e., <2% after vacuum cure. Superior fiber property translation. 180°F Wet service temperature after ~250°F cure Good tack and drape characteristics for 3 weeks at room temperature Applications/Qualifications: Primary Aircraft Structures Fuselage Wing Control Surfaces Secondary Aircraft Structures Aircraft Frames Doors Shelves Bulkheads Information provided by Park Electrochemical Corp.
