Organosilanes promote adhesion, mechanism

Fig. 31. 8 Increase in the delamination velocity as a function of mechanical stress in the blister test experiment measured with the HR-SKP comparison of an unmodified epoxy adhesive (as in Fig. 31.2, about 70 p,m thick) and of the adhesive modified with an organosilane adhesion promoter, performed with 0.5 M NaCi as electrolyte.

Although silane adhesion promoters are probably the most known, used, and versatile, there are many others. Some are based on titanium, chromium, or zirconium, while others, still based on silicon chemistry totally differ in their structure from regular organosilanes. This section will highlight briefly a few examples with their chemistry, mechanisms, and fields of applications.
