Binder and Solvent Recovery

icon youtube

Binder recovery allows to collect a sample of binder separated from the mix by solvent extraction. Thanks to the controlled atmosphere (vacuum or neutral gas) the binder is not oxidized by the process and can be used for binder tests. Most common binder recovery systems are the rotary evaporator and Abson method. Solvent can also be recycled by distillation and be reused for further binder extractions.
