Beschreibung
Zusammenfassung:	The present invention provides for a resin system and coating composition suitable for direct application to metal substrates. The composition may include a phosphate functional polyester. The polyester may be an unsaturated polyester polyol. The coating composition may further include a suitable curing agent, such as an isocyanate or melamine. The composition can be applied through traditional application equipment onto a variety of metal substrates and cures to an acceptable surface for further processing, such as top coating with basecoat and clearcoat. Cette invention concerne un système de résine et une composition d'enduction convenant pour une application directe sur des substrats métalliques. Cette composition peut inclure un polyester fonctionnel de phosphate. Le polyester peut être un polyol de polyester insaturé. La composition d'enduction peut comprendre également un agent durcissant convenable tel qu'un isocyanate ou de la mélamine. La composition peut être appliquée au moyen d'un matériel classique sur divers substrats métalliques et durcir à un niveau acceptable avant poursuite du traitement, telle que l'application d'un revêtement extérieur avec couche de fond et couche transparente.
