SikaBiresin® CR122

(former Biresin® CR122)

Biresin® CR122 is a medium viscosity epoxy resin system suitable for the production of high-performance fiber reinforced composites with a thermal performance up to 120°C.

  • Excellent impregnation and good non-draining properties due to optimized mixed viscosity.
  • Biresin® CR122 (A) with hardeners (B) Biresin® CH122-3 and CH122-5 are Germanischer Lloyd approved, certificate no. WP 1620018 HH.
  • Glass transition temperatures of up to 120°C are achievable depending on curing conditions.
  • Biresin® CR122 (A) with hardeners (B) Biresin® CH122-3, CH122-5 and CH122-9 are approved by Luftfahrt-Bundesamt (German Aeronautics Federal Office) as resin system for GRP, CRP and ARP parts for gliders and power gliders.
  • 3 hardeners with an uniform mixing ratio of 100:30 gives a range of processing times and processing flexibility. The reactivity can be adapted by mixing the hardeners.
  • Demoulding is possible after RT curing when using three fastest curing agents Biresin® CH122-1, Biresin®CH122-3 (B) and CH122-5 (B).
  • Hardener (B) Biresin® CH122-9 allows for a very long potlife but is only available in blue.

Usage

Biresin® CR122 systems are well suited to the hand lay-up process due to the optimized viscosity range for those processes. They can be used in the production of general industrial composites as well as in the production of composite tooling by hand lay-up and where temperature performance of up to 120°C is needed.
