A method of stabilizing imino-functional silane involving adding thereto at least one Brønsted-Lowry base to inhibit, suppress or prevent the addition reactions of the imino-functional silane with itself to form a imino- and amino-functional silane and the subsequent deamination reactions to form conjugated carbon-carbon double bond-containing imino-functional silanes and stabilized imino-functional silanes containing the at least one Brønsted-Lowry base.
The present disclosure invention relates to novel secondary aminosilanes, a method for producing same, and the use thereof. The secondary aminosilanes can be produced from readily available reactants in a simple manner. The secondary aminosilanes are characterized for example by a low viscosity and are well suited for producing silane-functional polymers that have a low viscosity, fast curing, and good thermal stability.

Aldimines of Formula (I), which can be used as latent curing agents in curing compositions, for example, in moisture-curing polyurethane compositions that have isocyanate groups. The aldimines are compounds that can be liquid at room temperature, can have a hardly noticeable aldehyde odor before, during and after hydrolysis, and can have a long shelf life. An aldehyde in polyurethane compositions that is released during hydrolysis has only a slight softening effect and can exhibit very little tendency to migrate or exude.
