WPI-124

(50% Propylene carbonate solution) Photo cationic initiators

Physical characteristics

Photocurable

  • Since it does not include heavy metals such as antimony, the toxicity is reduced.
  • Has a high curing performance similar to that of WPI-116.
  • There is no risk of HF generation due to the effect of moisture, therefore, no metal corrosion is expected.
