Abstract:
Die vorliegende Erfindung betrifft durch Kondensations- und/oder Additionsreaktionen härtbare Beschichtungszusammensetzung enthaltend (A) mindestens ein Polymer als Bindemittel, (B) mindestens ein Vernetzungsmittel, welches durch Kondensations- und/oder Additionsreaktion mit der Komponente (A) umgesetzt werden kann, sowie (C) mindestens einen speziellen Komplex als Katalysator. Die vorliegende Erfindung betrifft auch die Verwendung des Komplexes zur Katalyse der Härtung von durch Kondensations- und/oder Additionsreaktion härtbaren Beschichtungszusammensetzungen.
Abstract:
The present invention relates to an aqueous dispersion comprising cationic polyvinyl alcohol modified polymer particles, to aqueous electrocoating materials containing said dispersions and to a process to produce an at least partially coated substrate using said aqueous electrocoating material. The aqueous dispersion can be prepared by reacting an intermediate comprising at least one polyvinyl alcohol polymer chain with a compound comprising at least one epoxide group and a least two blocked primary amino groups. Aqueous coating compositions comprising said aqueous dispersion result in improved leveling properties during film formation as well as an improved edge protection of the substrate without negatively influencing the surface roughness and adhesion as well as the deposition properties.
