Product Description

  • Tg ~120°C
  • enables demoulding at room temperature
  • meets the standards of the European EASA construction rules (Part 22)
  • approved by Luftfahrt Bundesamt according RHV
  • with GL approval

Characteristics and Advantages

  • one resin with four hardeners with different reactivity
  • because of optimized mixed viscosity good impregnation and good non draining properties
  • demoulding is possible with Biresin® CH122-1, CH122-3 or CH122-5 hardener already after RT curing
  • glass transition temperatures up to 120°C dependent on curing conditions


  • For wet lay-up, pultrusion and filament winding processing
  • Specially for applications when higher temperature resistance is required
  • Biresin® CR122 with Biresin® CH122-3 and CH122-5 approved by Germanischer Lloyd for the production of components
  • Biresin® CR122 with Biresin® CH122-3, CH122-5 and CH122-9 approved by Luftfahrt-Bundesamt (German Aeronautics Federal Office) as resin system for GRP-, CRP- and SRP parts for glider and power glider
