The decrease in the optimum cure time with devulcanization time could be the result of better silanization by the fragmented TESPTs attached with DeVulcSBR, so that all silica surfaces are well covered with silane resulting in less acidity and polarity, which in turn prevent accelerator adsorption and decreases optimum cure time.
The recent development of Agilon by PPG has provided a route to circumvent the mixing issues (high mix temperatures required for the silanization step) associated with silica filled natural rubber compounds.
Following silanization, the cantilevers were washed in a series of acetone, isopropanol, and water, and then in order to remove excess APTES, they were soaked in deionized (DI) water for 15 min on an orbital shaker.

19) The reaction mixture was filtered through a sintered glass funnel and a filtrate was used in the silanization process applied to steel substrates for 1 h at room temperature.
Silanization of typical borosilicate-type glasses has often been done with alkoxy- or chlor-functional compounds such as 3-aminopropyltrimethoxysilane (APTES), dimethtyldichlorosilane (DMCS), or n-alkane-terminated trichlorosilanes.
This is due to the fact that only hydroxyl groups need to exist on the surface prior to silanization process by organosilanes [12].
As zirconia has a polycrystalline structure and limited vitreous phase, neither hydrofluoric acid etching nor silanization can achieve durable zirconia- resin bonding.
Since non-silica based Yttria partially stabilized tetragonal zirconia (Y-TZP) are resistant to etching [3], other techniques such as air-abrasion, silanization and laser irradiation are used to increase the roughness of zirconia surface [4].
