Abstract:
A process for preparing polyurethane carpet backings uses a filled polyurethane-forming composition that contains a mixture of certain metal acetylacetonate and sulfur-containing organotin catalysts. The mixture of catalysts is particularly beneficial in instances where the composition is processed at temperatures of above 30 to about 500 C, as long pot life is provided together with a rapid thermally-induced cure.
