V-50
CAS : 2997-92-4
Plastics manufacturing
Photocurable
V-50 is a highly active water-soluble azo polymerization initiator. A variety of polymerization applications can be expected. This product is uniquely characterized by the amidine group which is cationic. Cationic emulsions, latex, etc. can be synthesized easily and in a stable manner, therefore an excellent effect can be expected for emulsion polymerization of synthetic rubber, adhesives, etc.
- Water-soluble cationic azo initiator
- 10 Hour half-life decomposition temperature: 56℃(in water)
- Used for the superabsorbent polymer and coagulant
