Summaries

Aqueous polyurethane dispersions are used widely in the coatings industry because of their high performance. A new technology has been developed to achieve enhanced properties of aqueous urethanes and urethane-acrylics through the design of unique (self) crosslinkable polyols. Synthesis and properties of a wide range of urethanes and urethane-acrylics with varying crosslinking densities and structures will be discussed.

Zusammenfassung

Wässerige Polyurethandispersionen werden wegen derer Hochleistung bei der Beschichtungsstoffsindustrie weit benutzt. Um verbesserte Eigenschaften der wässerigen Urethane und Urethan-Alkyde durch den Entwurf der einigartigen (selbst-)vernetzbaren Polyole zu bekommen, wurde eine neue Technologie entwickelt. Es wird diskutiert die Synthese und die Eigenschaften einer brieten Reihe Urethane und Urethan-Alkyde mit verschiedenen Vernetzdicken und Aufbauen.

Résumé

Des dispersions de polyuréthannes aqueuses sont utilisées à gronde échelle aux industries de produits de peinture en vue de leur rendement élevé. Une nouvelle téchnologie a été développée pour augmenter les caractéristiques des uréthannes et uréthannes acryliques, grâce à la conception des polyols (auto-)réticulables. La synthèse et les caractéristiques d’une gamme large d’uréthannes et d’uréthannes acryliques ayant de diverses densités de réticulation et de structure seront discutées.
