Metal particles, e.g. aluminum, are treated with ionic organic phosphate, being thereby transformed to a state capable of resisting attack from an aqueous medium. The treated particles may be incorporated into a water-borne coating.

Water resistant aluminum particles and coating

Unique polished metal flake pigmented, plastic powder products produced, e.g. by a process including the measure of brush polishing metal flake particles and plastic particles together.

Metal-pigmented plastic powder

A method of using a powder product consisting essentially of thermoplastic or thermosetting polymer based plastic particles and mutually separated, metal flake particles which lie with their faces attached to the surfaces of the plastic particles, said method including applying said powder product to a surface and then melting the plastic particles to form a continuous film on the surface, this being followed by subsequent solidification of the film to obtain a coating of the surface. In an alternate form of the invention, the metal flake particles cover the plastic particles, the quantity of metal flake particles being such that coalescence is inhibited to give a rough, frosted metallic appearance to the surface.

Method of producing glossy or frosted powder coatings

A process for producing a polished metal flake pigmented, plastic powder product, which process includes brush polishing metal flake particles and plastic particles together. Unique products produced by this process.
