EUCosIngActivePolyurethane-68 is a complex polymer that is made by reacting the trimer of hexamethylene diisocyanate (HDI isocyanurate trimer) with PPG-30 Butyl Ether. Some of the remaining isocyanate groups from the first reaction are reacted with 2-pyridylethanol and in a third step, the remaining isocyanate groups are reacted with 1-isobutanol
