Ten percent of this base formula, utilizing a number of different catalysts, was charged to a quart can, the time required for the initiation of foaming was observed, and the resulting foam volume was measured. The results for these catalysts were: $G: Catalyst "Dabco" 33 LV DMAMP Dimethylamino Ethanol Diethylamino Ethanol No Catalyst $e: DMAMP appears to be more active than DMAE as a urethane catalyst, and should therefore provide significant cost savings in properly formulated foam systems.
