ABSTRACT:
Disclosed herein are compositions useful for introducing metal carboxylate salts as catalysts into systems useful for producing polyurethane and polyisocyanurate foams. The methods permit the introduction of such catalysts in the absence of substantial amounts of water which otherwise cause inferior foams to be produced. A method for producing foam employing the catalysts are also described.
