A composition that includes at least one silane-functional polymer P and 20 to 60% by weight of aluminum hydroxide or magnesium hydroxide or mixture thereof, is disclosed. The composition has a viscosity of 500 to 20,000 mPa&#xb7;s measured according to DIN 53018 at a temperature of 20&#xb0; C. The composition is suitable as a liquid membrane and has very good flammability properties, i.e., it is difficult to ignite and is self-extinguishing.

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.
