¢ºApplications
  Dabco NEM and NMM catalysts are extremely effective in the production of polyester-
based foams. These are due to their particular mechanism of catalysis which permits the gelling reaction to occur well beyond the completion of full rise, thereby maximizing cell openness. These morpholine derivative also exhibits good latitude in that the rise/gel ratio varies very little with changes in catalyst concentration. Therefore, slight metering errors are less detrimental to the quality of the foam.
