    Patent number: 6025029
    Abstract: A morpholine group comprising catalyst of the general formula, ##STR1## wherein n+m is >1 and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10, R.sub.11, R.sub.12, R.sub.13 and R.sub.14 are independently from each other hydrogen or an alkyl group, particularly a methyl or an ethyl group, is described. Said catalyst is particularly suitable for the use in storage stable polyurethane (PU)-compositions usable as adhesives, sealings, coatings or pretreatments with a primer. Said PU compositions have a delayed skinning time and thus an extended assembly time but nevertheless a fast development of strength, and they are suitable for the application on metal, glass, ceramics, wood, cementitious substratums and plastic substratums.
