<p>Described is a coating composition comprising at least a polycarbodiimide component having at least two carbodiimide groups per molecule, at least one anhydride component having one or more carboxylic acid anhydride groups per molecule, and a hydroxylic reagent capable of reacting with said anhydride component to generate free carboxylic polyacids, at least one among said components and reagents being a compound suitable for forming films. The composition produces fast cross-linking coatings at low temperatures.</p> |
