| | Methyltris(methylisobutylketoxime)silane Usage And Synthesis |
| Background | There has been a long felt need in the industry for tetrafunctional oximino silanes which do not require organic solvents or mixing with trifunctional oximino silanes. We have surprisingly discovered that the novel tetrakis oximino silane, e.g. tetrakis-(methyl isobutyl ketoximino) silane is liquid and thus do not suffer with the same problems as their solid counterparts. These new silanes offer the ability to employ solvent-free formulations, if not significantly decrease solvent content in the composition. In addition, there is added flexibility and simplification when formulating room temperature moisture-curable silicone compositions. Because the new silanes are liquid tetrafunctional oximino silanes, one can add more of these silanes to increase the cure rate of the composition. The amount of other tetrafunctional oximino silanes which can be used in this type of silicone composition is limited by their solubility in the solvent.
In addition to the novel liquid tetrafunctional oximino silanes, we have also found that when these novel oximino silanes (tetra-oximino, tris-oximino or bis-oximino) are formulated with hydroxyl terminated polydimethylsiloxane (HTPDMS), an optically clear silicone rubber results.
