    摘要: Polyurethane resin curable at low temperature and in a short time is prepared by contacting a compound having 1-oxa-3,5-diazine-2,4,6-trione ring as well as isocyanate groups, e.g. a reaction product of an aliphatic, alicyclic or aralkyl polyisocyanate, e.g. hexamethylene diisocyanate and carbon dioxide and a compound having active hydrogen, e.g. polyester polyol, with tert-amine, e.g. trimethylamine present in gaseous phase, at a temperature of 0-100°C. The ratio of the sum of the numbers of the trione ring and the isocyanate group to the number of the active hydrogen in the compound having the same is 0.1 to 10.

    摘要: The invention relates to foundry binder systems which use modified polyisocyanates. The modified polyisocyanates are prepared by reacting a polyisocyanate with an aliphatic alcohol having one active hydrogen atom. These modified polyisocyanates, along with a phenolic resole resin, are added to a foundry aggregate to form a foundry mix which is shaped and cured with a gaseous amine curing catalyst.
