the possibility of using γ-aminopropyltriethoxysilane (γ-APS) to increase the durability of epoxy powder coating/steel joints. The curing temperature of epoxy powder coatings is frequently above 200 °C, which is seen so far as a major limitation for the use of the heat-sensitive aminosilane coupling agent.

Most of the widely used organosilanes have one organic sub-stituent and three hydrolyzable substituents. In the vast majority of surface treatment applications, the alkoxy groups of the tri-alkoxysilanes are hydrolyzed to form silanol-containing species. Reaction of these silanes involves four steps.
