Having a surface coating made of a water-soluble polyamide filler

The present invention relates to a filler material, which excludes the layered silicate, the filler material having a surface coating, the surface coating comprising a water soluble polyamide or more water-soluble polyamide, wherein the water-soluble polyamide at least one prepared by the polycondensation of a monomer component, the monomer component comprising at least one dicarboxylic acid and at least one ether selected diamines, preferably having a linear propoxy - amino end groups. Such coated filler materials suitable for the preparation of filled and / or reinforced thermoplastic molding material. Comprising a filler material having a surface coating of such a thermoplastic molding material having good mechanical properties and emit less (low gas evolution).
