As a rule, larger alkyl groups on a silane will have lower VOC, and a higher alkoxy group will have lower VOC.
1] are reasonably attributed to the deposition of the silane coupling agent on the concrete surfaces, due to the stretching vibration of C--H in the alkoxy group from the coupling agent.
The alkoxy group was for the most part methoxy, although the aminosilane (Dow Corning Z-6011/Silquest A-1100) did offer ethoxy.
3], (where X is a hydrolizable alkoxy group, Y is a functional group, and R is a small aliphatic chain).
One end of the alkoxy group reacts with the silanol group on the silica surface via a hydrolysis mechanism (refs.
In this reaction, the end group of the ethylenic polymer will be the alkoxy group from the peroxide (figure 7).
Although the methoxy group is considered to be superior to diminish merely the silanol groups of the silica during the mixing in the silica-filled compounds, these results indicate that the ethoxy group is the best alkoxy group to improve the processing characteristics.
In the presence of moisture, hydrolizable alkoxy group leads to the formation of silanols.
The substitution of the alkoxy group not only enhances the delocalization [pi]-electrons in the copolymer, but also acts as a solubilizing group.
This step of reaction is basically a transesterification process where the exchange of the alkoxy group of an ester compound by another alcohol takes place.
First the alkoxy group in the coupling agent undergoes a hydrolysis process.
The difference is that the alkoxy group is bonded to one tin atom and the coordination of the carboxylate group takes place at a second tin atom, bonded with the first through an oxygen bridge.
