摘要：
The invention relates to powder coating leveling agents comprising (a) at least one polypropylene oxide-containing polyether having a weight-average molecular weight of more than 1000 g/mol and a polypropylene oxide fraction of more than 75% by weight, and optionally (b) at least one poly(meth)acrylate. The invention further relates to the preparation of such leveling agents and to their use in powder coating materials, and also to powder coating materials comprising the leveling agents.
