A method of catalyzing a cationic coating comprising a cationic resin such as an epoxy resin-amine reaction product or a copolymer of a cationic monomer, and a blocked polyisocyanate, wherein a catalyst is added, said catalyst selected from the group consisting of bismuth carboxylate(s) having a hydrocarbon chain of from 11 to 36 carbon atoms and a molecular weight of from 165-465, and a mixture of a bismuth salt selected from the group consisting of bismuth oxide and bismuth chloride, and a carboxylic acid having a hydrocarbon chain of from 11 to 36 carbon atoms and a molecular weight of from 165-465.

Metal salts of phosphoric acid esters as cross linking catalysts

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 novel complexes of zirconium or hafnium with diketones or alkylacetoacetoates. 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.
