V-40

Oil soluble Azo initiators

high-temperature typeoil soluble

Plastics manufacturing

Photocurable

Since the 10-hour half-life temperature is as high as 88 ℃, V-40 can be used to decrease residual monomer concentration when used with other initiators, such as V-65. This is an oil-soluble azo polymerization initiator which has a high solubility in various organic solvents. The decomposition product of V-40 has a unique characteristic of low volatility, therefore it could be useful for cow-voc paint applications.

  • Oil-soluble azo initiator having high decomposition temperature
  • Freely soluble in various organic solvents
  • 10 Hour half-life decomposition temperature: 88℃
