Park Electrochemical Nelcote® V-376 Cyanate Ester Epoxy Prepregs, 4503 Quartz Reinforced
Categories: Polymer; Thermoset; Epoxy

Material Notes: Nelcote® V-376 is a Cyanate Ester matrix providing excellent electrical and mechanical properties for harsh aircraft, shipboard, and undersea applications for Radomes, Antenna, and Reflectors. Simple processing and good handling characteristics make V-376 an ideal alternative to BMI and polyimide resin systems. GC110 LM qualified specifications.

Key Features and Benefits:

  • Cyanate Ester resin provides outstanding electrical properties (Dk, Df)
  • Excellent Moisture resistance properties
  • Simplified handling and processing characteristics
  • Minimal degradation of mechanical properties in Hot/Wet environments
  • Self-Adhesive to many types of foam and honeycomb core


  • Radomes
  • Reflectors
  • Antenna
  • Signature Control
