EVEN HALF THE ADVANTAGES OF
DABCO ARE I IMPRESSIVE
As a urethane catalyst, DABCO does a better job at less than half the concentration of conventional amines DEPENDABLE HIGH ACTIVITY. DABCO is a far more active DABCO®: H o u d r y Process catalyst for both polymerization and gas generating reactions than Corporation trademark for any other known amine. However, during the critical first 15 seconds triethylenediamine. of flexible foam formation, reactions catalyzed with DABCO have a C 6 H, 2 N 2 high exotherm rate while carbon dioxide evolution rate is comparatively low. This means that, at this stage, urethane polymerization is progressing much faster than gas generation—aPROCESS very desirable 1528 Walnut Street, Philadelphia C O conRPORATION dition in the production of one-shot foams. *Houdry means Progress...through Catalysis ECONOMY. It is unwise to base economy on catalyst cost. Concentration, scrap loss, and consistent production of premium quality PROCESS CORPORATIONt foam . . . these factors point the way to true economy and increased profit. PLANT SAFETY.
