Cas : 210290-42-9

Physical characteristics


  • 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.
