Catalysis plays an important role in the reactions of isocyanates. It is of vital importance in the manufacture of urethane and urethaneurea polymers in the form of foams, elastomers, coatings, sealants, adhesives, etc. Catalysis not only affects the rates of the chemical reactions responsible for the formation of these polymers, but it also exerts a considerable influence on their ultimate properties.
