ALUMINIUM GROUND FOR DONNES, PLASTIC EFFECTIVES, PROCEDURES FOR THEIR PRODUCTION AND USE

摘要

The invention relates to an atomized aluminum powder for thin, platelet-shaped effect pigments having a narrow relative breadth of the thickness distribution. The powder of the invention is characterized by a particle size band of d10=0.15 to 3.0 m and d50=0.8 to 5.0 m and also d90=2.0 to 8.0 m. The subject matter of the invention relates additionally to a method of producing the atomized aluminum powder of the invention, and to the use of the atomized aluminum powder of the invention as a laser marking agent or laser weldability agent for plastics. The subject matter of the invention relates additionally to the use of the fine atomized aluminum powder for producing ultrathin aluminum pigments by wet milling.
