Abstract

Methods of using an aldimine of formula (I) as cleaning agent or ingredient of a cleaning agent composition for reactive polyurethane compositions, especially for reactive polyurethane hot melt adhesives. It has been found that such cleaning agents can greatly reduce the quantity of wastes and in particular mixtures of blocked and nonblocked reactive polyurethane compositions can be used without problem for gluing, without the gluing being negatively influenced in its properties, especially its thermal stability.
