Biresin® CR120
Areas of Application
Product Benefits
For infusion or injection processing
Specially for applications when higher temperature resistance is required
Approved by Germanischer Lloyd for the
production of components
One resin with two hardeners with different reactivity
Uniform mixing ratio of 100 : 30
The reactivity can be adapted by mixing the
hardeners
Because of low mixed viscosity fast infiltration of
dry fabrics and nonwovens
Glass transition temperatures up to 120°C
dependent on curing conditions
