SikaBiresin CR122 is a laminating resin used for wet lay-up, pultrusion and filament winding processing. Especially for applications when higher temperature resistance is required.
Product Benefits
– 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 optimised 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 pot life but is only available in blue.
Areas of Application
– SikaBiresin CR122 systems are well suited to the hand lay-up process due to the optimised viscosity range for those processes.
– They can be used in the production of general industrial composites.
– For production of composite tooling by hand lay-up and where temperature performance of up to 120°C is needed.
