Abstract
A composite metal powder composition according to the present invention is a composition containing composite metal powder obtained in such a manner that an isocyanate compound is chemically bonded to the surface of surface-treated metal particles and a phosphorus compound is further chemically bonded to the isocyanate compound through an urethane bond and can be used as an excellent pigment for an aqueous paint. Further, the present invention simultaneously discloses a method of manufacturing the composite metal powder composition
Claims23
A composite metal powder composition, comprising surface-treated metal particles having a treated surface which is further chemically bonded with an isocyanate compound, wherein said isocyanate compound is bonded to a phosphorus compound through urethane bonding.
A method of manufacturing a composite metal powder composition, comprising reacting an isocyanate compound having at least two or more isocyanate groups with surface treated metal particles in an inert solvent and then adding thereto a phosphorus compound having at least one or more P--OH groups to react with the residual isocyanate whereby the surface of said metal particles is coated with the reaction product of said isocyanate compound and said phosphorus compound.
