Procedure

The 2-ethyl hexanol monourethane of 2,4-toluene diisocyanate was prepared by adding 1953 parts of 2-ethyl hexanol to 2610 parts of 2,4-toluene diisocyanate and 200 parts of methyl butyl ketone over a 5-hour period with agitation and external cooling to maintain the batch reaction temperature below 20° C. The batch was then thinned with 100 parts of methyl butyl ketone and stored under dry nitrogen.
