Beschreibung
Zusammenfassung:	The present invention is directed to novel metal organocomplexes as catalysts for the reaction of compounds with isocyanate and hydroxy functional groups to form urethane and/or polyurethane and the process employing such catalysts. More particularly, the present invention is directed to catalysts comprising a mixture of tetrakis-(2,4-pentanedionato) zirconium and a compound selected from the group consisting of a diketone: R1COCH2COR2 and R1OCOCH2COR2 wherein each of R1 and R2 is a branched or linear C1-C20 hydrocarbon and the total number of carbons in R1+R2 is at least 4. These novel catalysts are useful for the production of urethanes and polyurethanes which are important in many industrial applications, such as: coatings, foams, adhesives, sealants, and reaction injection molding (RIM) plastics.
