More Information
Summary:This invention relates to new diisocyanates containing urea groups which are liquid at room temperature or can be liquefied by heating to a temperature of up to 80 DEG C. These novel diisocyanates may be in the form of solutions in isocyanate prepolymers. The invention also is directed to a process for preparation of these new diisocyanates by the reaction of special diisocyanate starting materials and water and to their use as components for the production of polyurethanes.
