Sol-gel reactions do not employ extreme reaction conditions and the properties of the materials prepared using sol-gel approaches are easy to modify by utilizing an organically modified precursors.2,3 __Deposition Grade Silanes__ comprise alkoxysilanes and their predecessors chlorosilanes typically used in a Sol-Gel process. Transformations of alkoxysilanes during the processing proceed through a series of subsiquent hydrolysis, condensation and thermal treatment steps briefly outlined in __Figure 1__. ![alkoxysilanes](https://www.sigmaaldrich.com/content/dam/cms-commons/sigmaaldrich/marketing/global/images/technical-documents/articles/materials-science-and-engineering/microelectronics-and-nanoelectronics/alkoxysilanes.jpg "alkoxysilanes") __Figure 1.__Transformations of alkoxysilanes during the Sol-Gel process through a series of subsequent hydrolysis, condensation and thermal treatment steps. __Applications__ of *Deposition Grade Silanes* include but are not limited to - film coatings on glass and other appropriate surfaces1,4 - reinforcement of polymeric structures[1](https://www.sigmaaldrich.com/technical-documents/articles/materials-science/microelectronics-nanoelectronics/silane-sol-gel.html#ref), such as polyesters,16 Nafion®,17 Surlyn® - hermetic barriers for electronics and electrochemical devices5 - and others applications where Si-O-based chain assemblies are desirable.3,4 __Extensive analytical data__ available for Deposition Grade Silanes allow for a better understanding of chemical composition and properties of the materials created using these precursors as compared to those prepared form conventional silanes available commercially. __Purity__ of our Deposition Grade Silanes exceed 98%. They are fully characterized by chemical analysis and nuclear magnetic resonance (NMR). The impurities present in these materials are detected using a gas-chromatography (GC) and/or a GC-MS technique and reported on the Certificate of Analysis (CA). In addition, trace metals impurities are also reported on the CA. ## Trademarks Nafion is a registered trademark of The Chemours Company FC, LLC Surlyn is a registered trademark of E.I. du Pont de Nemours and Company ## Materials Sorry, an unexpected error has occurred Response not successful: Received status code 500 [](https://www.sigmaaldrich.com) [](https://www.sigmaaldrich.com) ### References 1\.
