Vern Currier sometimes tells customers not to use one of our products We're speaking of N-Ethylmorpholine in filled urethane foams. "For instance," Vern Currier (supervisor of our Urethane Technical Service Section) explains, "in a foam system based on THANOL® F-3002, b a r y t e s filler, a n d a triethylenediamine-stannous octoate catalyst combination, the use of THANCAT® NEM is not recommended." The above indicated catalyst combination for this filled foam system already has the proper balance in gelation and gas blowing reac-

tions . . . NEM is used widely in other formulations, however, and is very effective in promoting the gas blowing reaction. We have a healthy investment in urethane research and have given top priority to providing the right performance answers for all our THANOL polyols and THANCAT catalysts.
