Therefore, the technology was advanced to incorporate non-fugitivity and cell opening characteristics within a single catalyst. XF-N1085 is a novel cell opening blowing, non-fugitive catalyst which affords all the benefits of the well known Dabco BL-11, with the added advantage of cell opening and no foam emissions. XF-N1085 is not a drop in replacement for Dabco BL-11. 9 pphp. XF-O11006 is a novel cell opening gelling non-fugitive catalyst which gives all the benefits of the well known Dabco 33-LV, with the added advantage of cell opening, low volatility and no foam emissions.

Furthermore, Japanese wet set values [6] can be improved by 5 to 8% with the Dabco BL-53, and experimental silicone surfactants X-N1586 and X-N1587. Wet set values are improved nearly 20% when the two additives are utilised in combination as evidenced by Formulations IV and VIII.

Two experimental non-fugitive catalysts, XF-N1085 and XF-O11006 were developed to provide open foam and promote 42 Dimensional Stabilising Additives for Flexible Polyurethane Foams dimensional stability. During the development of non-fugitive catalysts, it was observed that TDI formulations, in general, tend to be more closed cell with the use of these catalysts compared to MDI systems. Therefore, the technology was advanced to incorporate non-fugitivity and cell opening characteristics within a single catalyst.
