V-601

Description

V-601 is a non-nitrile azo initiator having a high decomposition temperature. It is freely soluble in various organic solvents and has a 10 hour half-life decomposition temperature of 66° C.

It can be used as an alternative to V-60 (AIBN) as it has an equivalent polymerization activity which rises in alcohol solvents.
