Abstract

See full text

The present invention relates to heat-curing sealant compositions including at least epoxy resin, dicyanodiamide or an amine complex of a Lewis acid, polyurethane polymer (PUP) containing isocyanate groups and polyaldimine. These single component sealant compositions are characterized by a rapid skin formation and high tensile strength. Because of the short skin formation time, said compositions are optimally suitable for use as sealants in autobody work because they can be excellently layered on top of same.
