Zusammenfassung:	An aldiminosilane of the formula (I), to the use thereof as adhesion promoters and/or crosslinking agents, and to curable compositions including same. The aldiminosilane of the formula (I) is odorless, pH-neutral, liquid at room temperature, and has a low sensitivity to heat. The hydrolysis of the aldiminosilane proceeds relatively slowly, and the aldiminosilane is highly effective as an adhesion promoter. Furthermore, the aldiminosilane exhibits excellent compatibility with curable compositions based on isocyanates, epoxides, or silanes, whereby such compositions do not exhibit a propensity for migration effects such as bleeding or substrate soiling after being cured. In particular, isocyanate group-containing compositions containing the aldiminosilane of the formula (I) are highly storage-stable regardless of the storage temperature and the isocyanate used.
