Abstract
Isocyanate mixtures which are stable in the absence of moisture, and are curable by atmospheric moisture and which have low viscosities are obtained by mixing polyisocyanates containing biuret, allophanate or urethane bonds and functionalities in excess of 2 with monoisocyanates. These mixtures are used to coat substrates and the exposure of the coated substrates to atmospheric moisture results in cured coatings.
