ABSTRACT
Until recently, the coatings industry has relied mainly on organotin compounds for metal catalysis of NCO/OH reactions. With the development of new non-tin metal catalysts and with recent research of new and existing catalysts, it has become evident that catalyst selection is an important and complex issue that has become more complicated. These newly developed catalysts can provide new opportunities for managing old problems. This chapter is intended to provide a better understanding of the complexities of urethane catalysis and to develop guidelines for catalyst selection by troubleshooting commonly encountered problems.
