Abstract
A two-component composition is described which comprises A) an isocyanate component comprising an isocyanate-terminated urethane prepolymer, B) a water component comprising water, and at least one latent amine hardener in component A). The two-component composition of the invention is suitable as a sealant, in particular as a joint sealant. Particular advantages are that primerless application is possible with good adhesion, even at low temperatures, such as 4.4° C. or below. The substrate to be sealed are preferably concrete substrates.
