V-70 is an oil-soluble azo polymerization initiator of which a 10-hour half-life temperature is 30 ℃.
V-70 can be used as a polymerization initiator for different types of vinyl monomers and a catalyst for organic radical reactions at a low temperature.

  • Oil-soluble azo initiator having low decomposition temperature. An alternative to photoreaction as a radical generator.
  • Soluble in various organic solvents
  • With highest polymerization activity among azo initiators available in Wako
  • 10 Hour half-life decomposition temperature; 30℃
