Products for Polyurethane Resins

Product Summary

Oxetane ETERNACOLL® series are cationic curable raw materials with safety such as less hazard of skin irritation and lower toxicity. It can be used in combination with epoxy resins for a wide range of applications including coating and 3D printing resin.

*ETERNACOLL is a registered trademark in Japan and other countries.


  • Curable with UV/thermal cation generator or acid anhydride ⇒ No Influence of Inhibition with O2
  • Low Toxicity and Low Skin Irritation ⇒ Higher Safety
  • Good Compatibility with Epoxy compounds, and Improvement of Curing Speed of Epoxy Compounds by Combination with Oxetane ⇒ Expected to Contribute to High Speed Curing System and Good Properties of Cured Resin
  • Compounds Expected to Provide Low Curing Shrinkage ⇒ Improvement in Dimensional Stability and Adhesion
