Abstract
Disclosed is a polyurethane composition of multi-pack type, curable at ambient temperature, which comprises an isocyanate component having oxadiazinetrione ring, an active hydrogen component and a Lewis base whose basic site has no hydrogen active to NCO group and a process for producing polyurethane from the composition. The composition has excellent curability at ambient temperature and is useful for coatings, adhesives and elastomers as high solid content type or solventless type. The cured product polyurethane has good mechanical properties.
