Organosilanes which

This chapter presents a comprehensive review of the chemistry of organosilanes which have a nitrogen atom on the a-carbon in their structures. After presenting some elements relative to the structure, the synthesis, and the reactivity of SMAs in terms of making and cleaving bonds, their physicochemical and biological behaviors will be detailed. 

The sol-gel synthesis of hybrid organic-inorganic compounds usually involves a mixture of di- or trifunctional organosilanes, which introduce Si-C bonds, with metal alkoxides, mainly Si(OR)4, as cross-linking reagents to build the inorganic network. 

Hydrosilylation, the addition of a Si-H bond across an unsaturated carbon-carbon linkage, is a facile and atom-economical route to organosilanes, which can be functionalized further, for example, using the Tamao or Fleming oxidation protocol [33],... 

In an interesting interplay between GO and organosilanes (which are so extensively used to modify amorphous or nanostructured oxide surfaces), there are reports [33], of the preparation of intercalation compounds in which amino groups are inserted into the interlayer space of GO, using 3-aminopropylethoxysilanes. For such compounds, it was shown that the amino groups of... 

Three classes of primer are in current use surface protection primers , corrosion inhibition primers and organosilanes, (which are claimed both to protect the surface and enhance the adhesion). By far, the greatest numbers of commercial products fall into the second class. 

Adhesion promoters are used to provide good adhesion to such substrates as glass, hard plastics and certain metals, such as brass. These are specialised materials (e.g. organosilanes), which have the ability to promote adhesion to a substrate material at the same time as forming a part of the polymer network,... 

First and foremost, one shotdd make the distinction between all silanes molecules and the more specific organosilanes which are used in solutions or formulated systems as adhesion... 

Primers and adhesion promoters are normally low viscosity solutions of either isocyanate prepolymers or organosilanes, which function by surface penetration into and chemical adhesion to the substrate(s) and chemical adhesion to the subsequently applied adhesive or sealant, increasing bonding performance and durability. Again, formulators have developed ranges of primers to suit most adhesive or sealant and substrate combinations, and selection guides are widely available.
