Cold-curing, solvent-free, duroplastic two- and one-component polyurethane-polyurea compounds, comprising a) a (cyclo)aliphatic polyisocyanate, with NCO groups blocked with specific, sterically-hindered piperidine derivative, b) a primary and/or secondary di- and/or polyamine, where -in the case of one-component systems-the primary amino groups are present in blocked form as ketimines and c) polyester- and/or polyether polyols are useful for coating, sealing and encapsulating compounds. |
