Inhibitors

Characteristics

small dosagesinhibitors effects

The characteristic inhibitors of Wako are nitrosamine series. Q-1300 and Q1301 powerfully inhibit polymerizations even with very small dosages, thus they keep being stably effective during purifications and for the storage of highly reactive monomers.
