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.
