SikaBiresin® CR122
(former Biresin® CR122)
- Medium viscosity epoxy resin system
- Suitable for the production of high performance fibre reinforced composites
- 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 German 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 a 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 the three fastest curing agents Biresin® CH122-1, CH122-3 (B) and CH122-5 (B)
- Hardener (B) Biresin® CH122-9 allows for a very long potlife but is only available in blue
