The invention relates to aldiminoalkylsilanes ALS, which can be produced by reacting at least one aminoalkylsilane AS of formula (I) with at least one aldehyde ALD of formula (II). The invention also relates to a method for the production thereof, the use of said aldiminoalkylsilanes in compositions containing compounds which can react to amines, in particular polyurethane compositions, in addition to adhesive compositions. The aldiminoalkylsilanes ALS and the compositions containing the aldiminoalkylsilanes have a major advantage in that they have a low-odour or are odour-less and have a long storage life.
