Abstract
The invention relates to humidity hardening compounds containing at least one polyurethane polymer, P, exhibiting an isocyanate group, at least one polyimine ALD of Formula (I) of at least 22% by weight, in relation to the sum of the components of the compound which contain the isocyanate group, as well as, if necessary, a polyisocyanate oligomer OP. The humidity hardening compound is particularly suitable for providing coatings and linings. The use of the imines makes possible VOC-free or VOC-poor compounds, which is a substantial advantage for indoor applications.
