EVEN HALF THE ADVANTAGES OF

DABCO ARE 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 catalyst for both polymerization and gas generating reactions than an>r other known amine. However, during the critical first 15 seconds of flexible foam formation, reactions catalyzed with DABCO have a 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—a very desirable condition in the production of one-shot foams. ECONOMY. It is unwise to base economy on catalyst cost. Concentration, scrap loss, and consistent production of premium quality foam . . . these factors point the way to true economy and increased profit. PLANT SAFETY. For your eyes' sake, choose an amine catalyst with care. Insist on a complete toxicity report. Full data on DABCO sent on request. PERFORMANCE. More than 300,000,000 pounds of flexible and rigid urethane foams have been catalyzed with DABCO, the reliable catalyst chosen by foam producers in 22 countries.
