Abstract
(DE)
Beschichtungsstoffe für Coil-Coating-Verfahren, enthaltend (A) als Bindemittel mindestens einen aliphatischen, araliphatischen und/oder aromatischen Polyester mit einer Säurezahl von < 10 mg KOH/g, einer Hydroxylzahl von 30 bis 200 mg KOH/g, sowie einem zahlenmittleren Molekulargewicht Mn zwischen 1000 und 5000 Dalton, (B) als Vernetzungsmittel mindestens zwei aminogruppenhaltige Harze mit unterschiedlicher Reaktivität.Verfahren zu ihrer Herstellung und ihre Verwendung als Coil-Coating-Lacke.
(EN)
Disclosed are coating materials for coil coating methods, containing (A) at least one aliphatic and/or aromatic polyester having an acid number of < 10 mg KOH/g, a hydroxyl number of 30 to 200 mg KOH/g, and an average molecular weight (Mn) between 1000 and 5000 Dalton as a bonding agent, and (B) at least two resins which contain amino groups and have a different reactivity as crosslinking agents. Also disclosed are methods for the production thereof and the use thereof as coil coating enamels.
(FR)
L'invention concerne des matières d'enduction destinées à un procédé d'enduction en continu sur bande. Ces matières contiennent (A) comme liant au moins un polyester aliphatique, araliphatique et/ou aromatique ayant un indice d'acidité inférieur à 10 mg KOH/g, un indice d'hydroxyle de 30 à 200 mg KOH/g et un poids moléculaire moyen Mn compris entre 1000 et 5000 unités de masse atomique et (B), comme agent de réticulation, au moins deux résines contenant des groupes aminés de réactivité différente. L'invention concerne leur procédé de production et leur utilisation comme peinture d'enduction en continu sur bande.
