| Résumé : |
Polyurethane dispersion films are inherently more sensitive to moisture, however, when crosslinked they are an effective substitute for the solvent-based urethanes. Different crosslinkers, their activation temperatures, typical crosslinking mechanisms and advantages of these resins as grinding vehicles and paint extenders for both organic and inorganic pigments are shown. Also discussed is their formulation with a variety of other water-borne resins and with different crosslinkers to optimize their properties. Examples of different formulations and their properties both clear and pigmented are shown. |
