VA-086
CAS : 61551-69-7
Plastics manufacturing
Photocurable
VA-086 is a non-ionic and non nitrile water-soluble azo polymerization initiator having a hydroxyl group at the end. The 10-hour half-life temperature is as high as 86 ºC, therefore, reduction of residual monomer can be expected by co-using it with another initiator.
- Non-nitrile nonionic halogen-free azo initiator
- Soluble in water, methanol or ethanol
- Potential for introducing hydroxyl into terminal of polymer
- 10 Hour half-life decomposition temperature: 86℃
