While the kinetics of siloxane bond formation in aqueous systems have been studied extensively, there exists only sparse data on the equilibrium constant for siloxane bond formation gelets hydrolysis in aqueous media Scheme 1. Representative examples of classes of organofunctional silanes are depicted in structures 6 — 9.

On the other hand, phenomena, such as Ostwald ripening of Stober process silica particles and formation of monolithic structures by sol—gel processing, suggests that the equilibrium is much more balanced. The process was repeated for all the samples at specified intervals for ca. Several factors can potentially interfere with a straightforward determination of a silanol—siloxane equilibrium constant.

Further, contact-angle studies provide a simple metric that is readily related to the presence of a silane, whereas mechanical properties associated with composites and coatings are less direct. Trimethyl propoxy silane Gelestt C6h16osi Methyltris methylethylketoxime silane Examples of functional bridged dipodal silanes are bis trimethoxysilylpropyl amine and bis triethoxysilylpropyl tetrasulfide.

Dipodal silanes possess two silicon atoms that can covalently bond to a surface. Geelest A Silane 3-aminopropyltriethoxysilane Cas No.: The apparent equilibrium constant for the hydrolysis of one mole of disiloxane to two moles of silanol was calculated for each data set and then averaged, providing the result:.

The stability silanfs surfaces in aqueous environments prepared from dipodal silanes with hydrophobic alkyl functionality is compared to the stability of similar surfaces prepared from the conventional silanes.
