| Résumé : |
This study describes a novel paint technology that meets the recycling needs of industrial products. The decomposable crosslinking paint exhibits good properties throughout its use in the natural environment, and after use, it can be easily eliminated in a special process to recover the substrates. The paint was cured by a reaction between a carbonyl group of resins and a hydrazide group of crosslinking agents. The reverse reaction could be promoted by three essential components: water (reactive material), an acid (catalyst), and a solvent (diluent between active groups). The paint film was eliminated by dipping the paint in the solution containing these three components. The rates of dissolution were determined by water content, acid strength, swelling intensity of solvent, and dipping temperature. |
